I spent a couple hours this afternoon getting started with D3.js.
I worked my way through @mbostock’s block and bar chart tutorials. After completing each, I have much greater grasp on the svg elements and building some simple charts with D3.
All of the d3 blocks that I will be working on publicly will be available at http://bl.ocks.org/queuebit (although the bar chart block seems to be having some sort of caching issue at the moment).
Tomorrow, I plan on working on adding limited interactivity and working my way through three little circles and towards reusable charts.
