Where would one get started with building a graph like this? I’m trying to wrap my head around the code. Is there a simpler d3 example with less permutations that I can build upon?
I'm not a programmer and taught myself D3 last fall. Amelia Wagenbruger (sp?) has a good book too.
what you can do pretty easily is use and modify examples that seem to fit your needs.
but synthesizing from scratch isn't something very attainable and has a much steeper learning curve.
