This forum is for discussions on D3: Data-Driven Documents. Topics include visualization design, API design, requesting new features, etc. If you want help using D3, please use the d3.js tag on Stack Overflow!
For technical discussions, a link to a small, working example is far more helpful than pasting large chunks of code into email. (Small code snippets are okay.) For hosting examples, see JS Bin, JsFiddle and bl.ocks.org.
