Nesting and summarizing data is a very common task for data analysis. I thought it would be nice to view parallel ways of nesting and summarizing with both
tidyr and dplyrd3.js ...v4 for funTo avoid context switching, I'll take advantage of the R package V8. If you are an R user, then these d3.js gists might be helpful d3 nest examples and Mister Nester.

Although very handy and useful, I think most new R developers do not even know that tables exist. They are a little tricky to use, but they offer some nice functionality. These tables become even more useful when we can visualize them as networks. This little bit of code is a rough first attempt at converting tables to network nodes and edges.
