Improving data visualisation for the public sector - 0 views

  •  
    Welcome to the Improving data visualisation for the public sector project Good data visualisation can help users explore and understand the patterns and trends in data, and also communicate that understanding to others to help them make robust decisions based on the data being presented. This site supports public sector researchers improve the way that they visualise data, by providing good practice examples and case studies, practical and step-by-step guides on how to visualise data, and links to more detailed resources. http://www.improving-visualisation.org

Visualization contests around the corner - 0 views

  •  
    Visualization contests around the corner May 25, 2011 to Contests | Comments (3) The best way to learn how to visualize data is to grab a dataset and see what you can do with it. You can read as many tips and tricks as you want, but you're not going to get any better until you actually try. Contests are a fun way to do this. Participate So here are a handful of visualization contests to get your hands dirty. Hey you might even win a couple of thousand dollars. Not that money matters to you, because as well all know, learning is your reward. Hacking Education - A contest for developers and data crunchers. DonorsChoose.org has inspired $80 million in giving from 400,000 donors, helping 165,000 teachers at 43,000 schools, and the donation site has opened up this data. Can do you do something with it? Deadline: June 30, 2011. Data In Sight - A hands-on competition in San Francisco's SoMa district with surprise data sources. Some talks, lunch, dinner, and a 24-hour hackathon. Event date: June 24, 2011 (better to register your team early). Tableau Interactive Viz Contest - This one is coming up the quickest, but is the most straightforward. Plus, you get a t-shirt just for entering. Grab some business, finance, or real estate data and go to town with Tableau Public. Deadline: June 3, 2011.

Zanran Numerical Data Search - 0 views

  •  
    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.

Telling Stories With Data - 0 views

  •  
    Goals and Topics Our goal with this workshop is to bring together data storytellers from diverse disciplines and continue the conversation of how these different fields utilize each other's techniques and articulate principles for telling data narratives. Our target participants are researchers, journalists, bloggers, and others who seek to understand how visualizations support narrative, stories, and other communicative goals. Participants may be designers of such visualizations or designers of tools that support the creation of narrative visualizations. Visualizations that serve as a "community mirror" and thus create opportunities for discussion, reflection and sharing within a social network are also suitable topics. While we are inspired by many visualizations that display personal histories and storylines, our focus is on visualization situated in storytelling contexts, not necessarily visualizations of stories. Specific topics of interest may include, but are not limited to: Media and genres Embedding visualizations in social media to tell stories Multimodal storytelling with visualization (e.g. narrated or acted visualization, such as Rosling's Gapminder presentations) Non-traditional narrative - games and other procedural narratives incorporating data Visualization in (data)journalism - how news stories and visualization can complement each other Visualizations that support specific types of stories: Personal stories ("Here's a history of my cancer treatment") Community and collaboration stories ("How has our Facebook group changed over the past year?") Public data sets and narrative ("What is your Senator doing with your taxes?") Fictional, semi-fictional, and non-fiction stories

8 cool tools for data analysis, visualization and presentation - Computerworld - 0 views

  •  
    I came back from last year's National Institute for Computer-Assisted Reporting (NICAR) conference with 22 free tools for data visualization and analysis -- most of which are still popular and worth a look. At this year's conference, I learned about other free (or at least inexpensive) tools for data analysis and presentation. Want to see all the tools from last year and 2012? For quick reference, check out our chart listing all 30 free data visualization and analysis tools. Like that previous group of 22 tools, these range from easy enough for a beginner (i.e., anyone who can do rudimentary spreadsheet data entry) to expert (requiring hands-on coding).

Visual.ly | Infographics & Visualizations. Create, Share, Explore - 0 views

  •  
    Visual.ly - a new tool to create data visualisations July 28th, 2011Posted by Sarah Marshall in Data, Design and graphics, Handy tools and technology, Multimedia Visual.ly is a new platform to allow you to explore and share data visualisations. According to the video below, it is two things: a platform to upload and promote your own visualisations and a space to connect "dataviz pros", advertisers and publishers. Visual.ly has teamed up with media partners, including GigaOM, Mashable and the Atlantic, who each have a profile showcasing their data visualisations. You will soon be able to create your own "beautiful visualisations in minutes" and will "instantly apply the graphics genius of the world's top information designers to your designs", the site promises. Plug and play, then grab and go with our push-button approach to visualisation creation. The sample images are impressive, but journalists will have to wait until they can upload their own data.

Interactive Dynamics for Visual Analysis - - 0 views

  •  
    A taxonomy of tools that support the fluent and flexible use of visualizations Jeffrey Heer, Stanford University Ben Shneiderman, University of Maryland, College Park The increasing scale and availability of digital data provides an extraordinary resource for informing public policy, scientific discovery, business strategy, and even our personal lives. To get the most out of such data, however, users must be able to make sense of it: to pursue questions, uncover patterns of interest, and identify (and potentially correct) errors. In concert with data-management systems and statistical algorithms, analysis requires contextualized human judgments regarding the domain-specific significance of the clusters, trends, and outliers discovered in data.

Corporate Accountability Data in Influence Explorer - Sunlight Labs: Blog - 0 views

  •  
    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
