The thing about D3 is...

It isn't a visualisation library

What is it?

One-way data binding
Excels at transition states
Provides lots of helpers for visualisations

How to use it

var figures = [
  { "name": "Triangle", "numPoints": 3, "perimeterRatio": 4.55 },
  { "name": "Square", "numPoints": 4, "perimeterRatio": 4 },
  { "name": "Pentagon", "numPoints": 5, "perimeterRatio": 3.81 },
  { "name": "Hexagon", "numPoints": 6, "perimeterRatio": 3.72 }
];
