Hello, this is the Open Flash Chart project. Note: "Open Flash Chart 2" is LGPL. OK, Open Flash Chart 1.x was great and it works like a dream. But I made some little mistakes which over time grew and anyoyed me and made the source code weird. So I decided it was time to re-jigger the code and make it pretty again. The big change is moving the data format to JSON. This has made a big difference and has allowed some pretty cool new features. While I was hacking away at the source code I moved it all to Actionscript 3, and used Adobe Flex to compile it. This means everything is open source. If you want to make changes to the charts all you need is laid out in these instructions. Just because there is a new version doesn't make V 1.x obsolete. You can use both versions at the same time so leave your current working code in V 1.x and make all the new charts using which ever version you find easier to use. Why is V2 better? Well it uses JSON as the file format and this means you can do cool stuff like Grant Slender has: http://code.google.com/p/ofcgwt/ If you like Open Flash Chart and want to see it continue, please help Donate some money :-) Blog about it (promotion takes up about a third of my time) Write a cool library Really. You can make a massive difference to the project! Need help choosing reseller hosting for your charts? Make sure you read reliable web hosting reviews. Why choose Open Flash Chart? This is a little gentle propaganda for the project. Like all opinions, disregard it and make up your own mind. Edge cases such as tooltips encourage user interactivity and data exploration what happens to the tooltip when two points are in the same position? you can re-size the charts missing data save the chart as an image You can highlight or emphasize one (or many) points PC Pro loves open flash chart.

How to make searchable, Web-based Google charts Michelle Minkoff by Michelle Minkoff Published June 3, 2011 12:01 am Updated June 2, 2011 10:22 pm A lot of data visualization requires the technical expertise of a programmer and skills that take time and resources to develop. A rise in free tools, however, has made it easier to make interactive graphs in charts, whether you're a designer, developer, Web producer or hobbyist. The Google Visualization API, for instance, gives you options without making the work too complicated. I've created a tutorial below to help you make simple, Web-based Google charts. (You can click on any of the screenshots to go to a larger version.) In the first example, we'll craft an interactive bar chart that compares the numbers of tornado-related deaths in the United States throughout the past four years. We'll use data from the National Oceanic and Atmospheric Administration (NOAA), which can be found here. (You can download a cleaned version of this data here, formatted as a comma-delimited file, CSV.) http://www.poynter.org/how-tos/newsgathering-storytelling/126595/how-to-make-simple-web-based-google-charts

DIVA-GIS DIVA-GIS is a free computer program for mapping and geographic data analysis (a geographic information system (GIS). With DIVA-GIS you can make maps of the world, or of a very small area, using, for example, state boundaries, rivers, a satellite image, and the locations of sites where an animal species was observed. We also provide free spatial data for the whole world that you can use in DIVA-GIS or other programs. You can use the discussion forum to ask questions, report problems, or make suggestions. Or contact us, and read the blog entries for the latest news. But first download the program and read the documentation. DIVA-GIS is particularly useful for mapping and analyzing biodiversity data, such as the distribution of species, or other 'point-distributions'. It reads and write standard data formats such as ESRI shapefiles, so interoperability is not a problem. DIVA-GIS runs on Windows and (with minor effort) on Mac OSX (see instructions). You can use the program to analyze data, for example by making grid (raster) maps of the distribution of biological diversity, to find areas that have high, low, or complementary levels of diversity. And you can also map and query climate data. You can predict species distributions using the BIOCLIM or DOMAIN models.

Again, US-centric, but this might generate some ideas of what could be accomplish in your city/nation. Late yesterday we announced a bunch of new features for Influence Explorer: http://sunlightlabs.com/blog/2011/ie-corporate-accountability/ As the blog post explains, you can now find information about a corporation's EPA violations, federal advisory committee memberships, and participation in the rulemaking process -- all in one place. I wanted to highlight that last feature a bit more, though. To my knowledge, this is the first time that the full corpus of public comments submitted to regulations.gov has been available for bulk download and analysis. This isn't a coincidence: regulations.gov is built using technologies that make scraping it unusually difficult. This is unfortunate, since everyone seems to agree that federal rulemakings are gaining in importance -- both because of congressional gridlock that leaves the regulatory process as a second-best option, and because of calls to simplify the regulatory landscape as a pro-growth measure. It's an area where influence is certainly exerted -- rulemakers are obliged to review every comment -- but little attention is paid to who's flooding dockets with comments, and which directions rules are being pushed. It's taken us several months to develop a reliable solution and to obtain past rulemakings, but we now have the data in hand. We plan to do much more with this dataset, and we're hoping that others will want to dig in, too. You can find a link to the bulk download options in the post above -- the full compressed archive of extracted text and metadata is ~16GB, but we've provided options for grabbing individual agencies' or dockets' data. If anyone wants the original documents (PDFs, DOCs, etc) we can talk through how to make that happen, but as they clock in at 1.5TB we'll want to make sure folks know what they're getting into before we spend the time and bandwidth. Finally, note that we currently o

Open Data Cook BookMaking Open Data Accessible for EveryoneAbout the Cook BookThe open data cook book is collecting recipes for ways to find and use open data, particularly open data of social value - such as open government data, or open data for campaigners and charities. Working with data can seem scary. But it doesn't have to be. There are many different ways to make data useful - and lots of different gadgets to help you. Take a look at the growing list of cook book recipes to find simple step by step ideas for making use of open data. RecipesYou can find a list of the recipes so far here. Drafts, ideas and notesIn the cooks notebook you can find draft notes on using different datasets and sketches that might develop into recipes in future.

Tweet with the #opendatacookbook tag, or bookmark content on del.icio.us 'opendatacookbook ' to share with the project. Join the mailing list to discuss developments. UpdateAfter a brief experiment with Drupal as a CMS for the cook book - we've switched to DokuWiki for a bit to make compiling a list of recipes a lot easier before we work out the best way to run the Cook Book.

"RegExr is an online tool for editing and testing Regular Expressions (RegExp / RegEx). It provides a simple interface to enter RegEx expressions, and visualize matches in real-time editable source text. It also provides a handy RegExp snippet sidebar with descriptions and usage examples to make it easier to learn Regular Expressions through trial and error. It isn't as powerful as a product like RegExBuddy, but it has the advantage of being online and free. I will be releasing a free desktop version for Mac OSX and Windows built with AIR in the next day or two. So far this has only taken a day of development, and the main app is only 150 lines of code. Flex 3 makes this kind of app so darn simple to put together."

Flare's design was adapted from its predecessor prefuse, a visualization toolkit for Java.

8 must-reads detail how to verify information in real-time, from social media, users Craig Silverman by Craig Silverman Published Apr. 27, 2012 7:46 am Updated Apr. 27, 2012 9:23 am Over the past couple of years, I've been trying to collect every good piece of writing and advice about verifying social media content and other types of information that flow across networks. This form of verification involves some new tools and techniques, and requires a basic understanding of the way networks operate and how people use them. It also requires many of the so-called old school values and techniques that have been around for a while: being skeptical, asking questions, tracking down high quality sources, exercising restraint, collaborating and communicating with team members. For example, lots of people talk about how Andy Carvin does crowdsourced verification and turns his Twitter feed into a real time newswire. Lost in the discussion is the fact that Carvin also develops sources and contacts on the ground and stays in touch with them on Skype and through other means. What you see on Twitter is only one part of the process. Some things never go out of style. At the same time, there are new tools, techniques and approaches every journalist should have in their arsenal. Fortunately, several leading practitioners of what I sometimes call the New Verification are gracious and generous about sharing what they know. One such generous lot are the folks at Storyful, a social media curation and verification operation that works with clients such as Reuters, ABC News, and The New York Times, among others. I wrote about them last year and examined how in some ways they act as an outsourced verification service for newsrooms. That was partly inspired by this post from Storyful founder Mark Little: I find it helps to think of curation as three central questions: * Discovery: How do we find valuable social media content? * Verification: How do we make sure we c

What is it? A social analytics platform which contains over 1,000 days of tweets (all 70 billion of them), Facebook activity and blog posts. How is it of use to journalists? "Journalists can easily develop real-time insights into any story from Playground," PeopleBrowsr UK CEO Andrew Grill explains. Complex keyword searches can be divided by user influence, geolocation, sentiment, and virtual communities of people with shared interests and affinities. These features - and many more - let reporters and researchers easily drill down to find the people and content driving the conversation on social networks on any subject. Playground lets you use the data the way you want to use it. You can either export the graphs and tables that the site produces automatically or export the results in a CSV file to create your own visualisations, which could potentially make it the next favourite tool of data journalists. Grill added: The recent launch of our fully transparent Kred influencer platform will make it faster and easier for journalists to find key influencers in a particular community. You can give Playground a try for the first 14 days before signing up for one of their subscriptions ($19 a month for students and journalists, $149 for organisations and companies).

"TransparencyCamp '11 Recap Nicole Aro May 4, 2011, 11:28 a.m. Sunlight's fourth TransparencyCamp was this past weekend, and I'd like to take this moment to say to all of our attendees: Thank you -- you guys rock. To everyone else, I'm sorry that you missed such an awesome weekend, but we hope to see you next time around! This weekend was made possible by the generosity of our sponsors: Microsoft, Google, O'Reilly, Governing, iStrategyLabs, Forum One, and Adobe. I'd like to say a special thank you to Patrick Svenburg of Microsoft who stayed late to make sure we could finish setup and even helped us carry supplies(!). The weekend brought together about 250 government workers, software developers, investigative journalists, bloggers, students and open government advocates of all stripes to share stories, build relationships, and plan together to take on the challenges of building more open government. This year, TransparencyCamp also went global, bringing in 22 amazing transparency advocates from around the world to teach, learn and share with us here in the states. "

Zanran helps you to find 'semi-structured' data on the web. This is the numerical data that people have presented as graphs and tables and charts. For example, the data could be a graph in a PDF report, or a table in an Excel spreadsheet, or a barchart shown as an image in an HTML page. This huge amount of information can be difficult to find using conventional search engines, which are focused primarily on finding text rather than graphs, tables and bar charts. Put more simply: Zanran is Google for data. Language. English only please... for now. Phrase search. You can use double quotes to make phrases (e.g. "mobile phones"). Booleans. You can use a plus '+' to make a word mandatory, or a minus '-' to exclude it (e.g. +gas -oil production) Vocabulary. We have only limited synonyms - please try different words in your query. And we don't spell-check ... yet.

OpenData Open Data

Constructing the Open Data Landscape Posted on September 7, 2011 by Nicola Hughes In an article in today's Telegraph regarding Francis Maude's Public Data Corporation, Michael Cross asks: "What makes the state think it can be at the cutting edge of the knowledge economy". He writes in terms of market and business share, giving the example of the satnav market worth over $100bn a year yet it's based on free data from the US Government's GPS system. He credits the internet revolution for transforming public sector data into 'cashable proposition'. We, along with many other start-ups, foundations and civic coding groups, are part of this 'geeky world' of Open Data. So we'd like to add our piece concerning the Open Data movement. Michael has the right to ask this question because there is this constant custodial battle being fought every day, every scrape and every script on the web for the rights to data. So let me tell you about the geeks' take on Open Data.

"Data docs is a video platform that allows filmmakers and journalist to combine elements from the web, such as interactive graphics, text and scraped information, with linear media, such as video and audio. Having worked in video both in long-form documentary and web video, we understand the power of visual media. Videos are powerful vehicles that we can use to tell personable or explanatory immersive stories. But one of the drawbacks of video as a medium is that they are finished products, which, after they have been published, become outdated fairly quickly. Advances in technology and data bases has allowed for data to be more flexible than video. Data visualizations and interactive infographics, for instance, can be up-to-date at any moment in time if they are hooked up to the right data bases. Think of charts of stock markets that updated every millisecond because APIs or other technological mechanisms feed them live data. We wanted to combine those two worlds - the world of immersive video storyelling and that of live and constantly updated data. This is why we created Data Docs. Through the Data Docs code library filmmakers and developers can 'hook up' their video to live data and other up-to-date information from the web. The library also allows you to integrate your own interactives with specific fonts and styles into your video. It enables you to project HTML, CSS and JavaScript-based graphics on your video. This helps you make videos that will never be out of date or, in other words, to make videos that are evergreen."

Make it easy for your organization to publish and manage public data You can achieve your organization's transparency goals, cost-effectively, by streamlining the data publishing process and automating maintenance and updates. Internal stakeholders, in any department or agency, with little or no technical assistance, become first-class data publishers. While administrators manage the organization's data in one central location, offer constituents a consistent and privately-branded online experience and get real-time data consumption and citizen engagement metrics.

Perception: Gestalt Laws Home → Data visualization for Excel users → Perception: Gestalt Laws Every chart starts with a table. We transcribe this table into a visual representation of distances between data points: the "origin chart". That's when our "eye-brain system" starts making assumptions. It assumes that data points are somewhat related, even if they are not:

Beautiful but Terrible Pyramids: Tableau Edition by Jorge Camoes on July 12, 2011 Well, here is my first chart in Tableau, finally! After publishing my experiments with population pyramids (using Excel), I thought I could try Tableau Public with the same dataset from the US Census Bureau. Here is the result. I never really played before with Tableau Public and it took my less than an hour to upload the data and make this chart, without reading a manual or watching a tutorial (changing line colors was the hard part). It says a lot about its usability. http://www.excelcharts.com/blog/beautiful-but-terrible-pyramids-tableau-edition/?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+JCCharts+%28Excel+Charts+Blog%29
