This stacked bar chart shows how movie ratings are distributed across six genres, with each bar divided into five rating categories from below 5.0 to above 8.5. The chart uses d3.stack() to create the stacked segments, d3.scaleBand() for the genre axis, and a d3.scaleOrdinal() for color encoding. Interactive tooltips appear on mouseover, displaying the precise percentage for each rating category within a genre. The data comes from an external CSV file, and the SVG rendering uses D3 v7 with custom styling from a CSS file.
