A very good collection of dataviz tips and tools

Tom Torok (NYT) writes: After years of looking down my nose at Excel because of its limitations, I have to say that I'm very impressed with Excel 2010 when used with a free Microsoft add-in called PowerPivot. http://office.microsoft.com/en-us/excel/download-powerpivot-HA101959985.aspx In a PowerPivot tutorial (link below), I imported eight tables  from several sources and joined them - yes, you can join relational data. It uses some magical data compression that allows for lightning fast sorts, filters and calculated fields. The largest table in the tutorial has about 2 million rows. A calculated field on that table took seconds. A did a pivot table on the table and the answers appeared as soon as I selected the fields. In one of  the training videos (http://www.powerpivot.com/) an MS guy works with a 101 million-record table on his laptop. It's really amazing. http://powerpivotsdr.codeplex.com/ If you install, be sure to read the prerequisites or you'll be installing and uninstalling both PowerPivot and Excel. I'm running it on a 32-bit XP machine (it won't run on a 64-bit XP but will work on Windows 7 64-bit). The tutorial is for a Windows 7 setup, but there are items in the menu bar that match the reference to the tutorial's ribbon. I noticed that if I call up an xlsx by double clicking on a file in Windows Explorer that PowerPivot is not enabled in the ribbon. If you call up a file from within Excel 2010 everything works as advertised.Regards, TT  

"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of the drawbacks of video as a medium is that they are finished products, which, after they have been published, become outdated fairly quickly.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."
