This area chart displays the distribution of movie ratings across six genres, with each genre’s proportional share of five rating categories stacked over the rating scale. The visualization uses D3.js v7 with a stacked area generator, `d3.stack()`, `d3.area()`, and `d3.scalePoint()`/`d3.scaleLinear()` for axes. Data is loaded from a remote CSV via `d3.csv()`, and the SVG render includes gridlines from axis tick marks, colored genre regions, and a legend listing each genre.
