This example visualizes the top movies and their ratings using a pie chart, with each slice representing a movie and its size proportional to the rating value. The chart renders as an SVG, using D3.js v5's `pie` and `arc` generators to create the segments and a color scale for differentiation. Ratings are loaded from a CSV file via `d3.csv`, and a legend on the right displays each movie's name alongside its corresponding rating value, formatted with `d3.format`.
