This pie chart visualizes population figures for US states, displaying each state as a colored slice with its population value labeled in millions. The chart uses d3.pie() to compute angular segments and d3.arc() with an inner radius of zero to generate the SVG paths. A legend is rendered to the right, mapping each state name to its corresponding color and population value. The data is loaded as CSV from a GitHub gist, and colors are assigned using d3.scaleOrdinal() with a predefined array of ten distinct colors.
