问题
I'm trying to convert a d3.js visualization to canvas. The d3.js code can be found here: https://gist.github.com/3166265
Could somebody explain the basics of converting this visualization to canvas? I cannot use a program like canvg because the browser I'm targeting (android platform 2.3) cannot parse any SVG AT ALL. Therefore I need to convert this visualizatoin to Canvas. Any help that you can provide would be most appreciated...
