D3.js Step by Step

Check out the tutorial.

NOTE: Examples now target D3 v4.

Here's what changed in this repo from v3 to v4:

• d3.scale.category20b() became d3.scaleOrdinal(d3.schemeCategory20b)
• d3.svg.arc() became d3.arc()
• innerRadius() needs to be explicitly defined so it is now .innerRadius(0) for the pie chart
• d3.layout.pie() became d3.pie()
