This year I did a session on using D3.js with the Visual Studio Online REST API showing how you could use it to generate charts. I meant to record a screen cast of the session but I forgot to hit record! My bad. Sorry about that.
I’ll do a blog series on this to make it clearer, but until I get it all written up and ready to go, I’ll leave you with this webcam recording of the presentation. I hope you find it useful!
