Program to make this sort of chart?

[Brandon138]

Wasn't exactly sure where to put this.

I want to make a chart similar to this...

but so I can constantly add categories to the different levels of it and the sections automatically equal out. Like I could make it in paint or something, but if I went to add things later there'd be no room. I'd like one i could constantly modify.

You can do this in R with the ggplot2 package and geom_polar (or a number of other ways like 'sunburst') but requires some programming experience. Probably there are some other programs on the web that can do this for you as well (but probably not free).

I also might add that radial charts are not a good method of presenting hierarchical data. A tree diagram is easier for example..

Also i know of http://gephi.org/ but never use it since R exists

An easy way to construct this graph is by using D3js -- it's a little easier than using R, as the templates are documented for lay individuals.
