Brouhaha: D3 Basics & D3 Mapping

D3 is awesome. When I first saw it, I'd never seen anything like it, and I learned it as quickly as I could so I could sell a client on its use. Even if you know javascript well, it can still take a while to add D3 to your proverbial Bat Belt, so we've put together a two part presentation on 1) the basics of D3 and 2) creating maps with D3.

D3 Basics:

Will Carroll the principal at develop_for is both a developer and designer. He has a background in design and development working with organizations, which include Ogilvy, Razor Fish, National Geographic, National Environmental Education Foundation and the DC Government to name a few. Will focuses on developing for data, data visualizations and web applications to help people understand the data to make better decisions.

D3 Mapping:

Trevor is a full stack developer and designer at Conveyal where he builds transit information software products including visualization tools and journey planning engines.

In case you're a little new to D3, it began in 2009 based on Prefuse and Flare, creating Protovis, a JavaScript library to generate SVG graphics from data. In 2011, the development of Protovis evolved into D3.js. Designed to provide a more expressive framework that, at the same time, focused on web standards and provides improved performance (Bostock, Heer & Ogievetsky 2011).

      There will be live demonstrations, but no need for your laptop. If you're interested in hands-on, look for more events like this:­
