This example shows the top 10 heroes in the Tollywood industry as an interactive SVG pie chart, with each slice labeled with the hero’s movie count and a corresponding legend listing names and values. The chart uses `d3.csv` to load data from a GitHub Gist, `d3.pie` and `d3.arc` to compute and draw the arcs, and `d3.scaleOrdinal` to map movie counts to a custom color array. It also employs `d3.select` and `d3.format` for SVG rendering and axis-tick formatting, respectively.
