A pie chart visualizes the distribution of movie genres by the number of films rated above 8.5, loading data asynchronously from a remote CSV file via `d3.csv`. The chart uses `d3.pie` to compute arc angles and `d3.arc` to generate SVG paths, with colors assigned by a `d3.scaleOrdinal` using `d3.schemeCategory10`. A legend on the right displays each genre with a colored square and label. The SVG is rendered with a fixed width of 800 and height of 450, and the visualization highlights proportional genre shares with semi-transparent, black-stroked slices.
