About Dataviva

MIT's César A. Hidalgo has just told me of Dataviva, a tool built with Python, HTML5, and CSS3 (running on d3plus) that lets readers explore tons of Brazilian data sets. Apparently, it began as a tool to visualize data just from Minas Gerais, one of the largest states in Brazil, but it now incorporates information from the entire country.

Dataviva should be invaluable for journalists and news designers. I've been playing with it this morning, and I'm delighted. The tool lets you switch between many different graphic forms (maps, dot plots, scatter plots, etc.,) it provides multiple ways to filter and reorganize the data, and it allows you to download the results of your exploration as CSV, SVG, PDF, and PNG.

This last feature is still a bit buggy. I got a couple of error messages while trying to generate an SVG to manipulate in Adobe Illustrator. However, at the end I'm a persistent guy I made it work, as you'll see in the pics below (yes, pie charts; I know.)

See a launch video here.
