This pie chart displays the distribution of scores across different genres, using platforms as slice labels. It loads a CSV dataset from a GitHub gist via `d3.csv`. The chart uses the `d3.pie` layout and `d3.arc` generators to create SVG paths, with colors assigned through `d3.scaleOrdinal` and `d3.schemeCategory10`. Hovering over a slice triggers a mouseover event that displays the Action value at the arc’s centroid using `arc.centroid`.
