D3 Examples - Radar Chart Redesign

Radar Chart Redesign
A new design for a radar chart in D3.js. You can read more about in on the blog Nadieh Bremer wrote "A different look for the D3 radar chart"
An older version of a radar chart that I adjusted two years ago when I was just starting to learn D3.js can be found here
