This visualization displays a pie chart of the top 10 movie directors by number of directed films, with each slice labeled by its count and a legend identifying directors. The chart uses D3.js v6’s `d3.pie` and `d3.arc` to compute and render the SVG paths, while `d3.rollup` aggregates the CSV data from a GitHub Gist. A categorical color scale (`d3.scaleOrdinal`) with `schemeCategory10` colors the slices, and the title and legend are appended as SVG text elements.
