legend = FALSE

Often the legend in the sunburst becomes useless with lots of nodes and multiple levels. While a hack could turn it off, I don’t like having to ask users to resort to hacks, so now the argument legend = FALSE will turn it off.

Kevin Warne has built an incredible sunburst in d2b, so I just had to add it to sunburstR. I think Kevin’s work definitely deserves a star on Github, and with only 32, I encourage a quick detour to share the love.
