This stacked bar chart shows the percentage distribution of IMDb rating levels within six movie genres, with hover tooltips revealing exact percentages. Each genre’s stacked bars represent five rating bands, from “below 5.0” to “above 8.5,” totaling 100%. The visualization uses D3 v7’s `d3.stack()` to compute stacked series, `d3.scaleOrdinal` for color mapping, and `d3.scaleLinear` and `d3.scaleBand` for axes. SVG rectangles render the bars, and mouse events trigger tooltip display with formatted percentages using `d3.format`. Data comes from a CSV file containing pre-aggregated genre ratings.
