4.3 Arcs

We’ll draw the pie chart with SVG arcs. D3 has a number of helper functions to make this easier—in this lesson I’ll show you how to use them. You’ll learn about d3.svg.arc, d3.layout.pie, and how to use radius values to scale your chart. I’ll also show you how to use some of D3’s helper functions for generating good-looking color themes.
