A stacked bar chart displays the percentage distribution of IMDb rating levels across six movie genres, showing how genres like Documentary skew toward higher ratings while Action clusters at lower ones. Built with D3 v7, the chart uses a linear x-scale for percentages, a band y-scale for genres, and an ordinal color scale for rating categories. Hover interactions trigger tooltips with exact percentages via D3 event handlers, while SVG rectangles render the stacked data from a CSV file loaded with `d3.csv`.
