This pie chart visualizes global sales data for the top ten PlayStation 4 games, sorted by total units sold. It uses D3.js (v5) within a React framework to render an SVG with a pie chart and a corresponding legend, showing each game's genre and total units. The code employs `d3.pie` and `d3.arc` to generate the segments, and `d3.scaleOrdinal` with `schemeCategory10` for coloring, with data loaded via `d3.csv` from a GitHub repository.
