Radar Chart D3 V4

A redesign of the radar chart function that was created by alangrafu, used in my blog on Making the D3 Radar Chart look a bit better

An even newer version created 2 years later can be found here

forked from nbremer's block: D3.js - Radar Chart or Spider Chart - Adjusted from radar-chart-d3

forked from alandunning's block: Radar Chart D3 V4
