Hi,

I am trying to get this piechart to work with D3 v4 but I am not succeeding. There are the obvious things that I need to change to make it compatible such as d3.layout.pie -> d3.pie but when I make these changes the graph doesn't plot anymore. Have you had this problem? Do you know how to fix it? Thanks Ryan
