This example shows a pie chart displaying program contributions to tuition revenue, with dollar amounts abbreviated in thousands and a color-coded legend identifying each program. The visualization is built with D3 v6, using `d3.csv()` to load billing data from a remote GitHub CSV file, `d3.group()` and `d3.sum()` to aggregate billing by program, and `d3.pie()` with `d3.arc()` to generate the arcs. Labels are positioned at arc centroids, and the SVG output includes a bold title and formatted text elements for clarity.
