This stacked bar chart shows the percentage distribution of movie ratings across six genres, revealing how genres like Documentary skew toward higher ratings while Action films cluster below 5.0. Each bar is segmented by five rating brackets, with tooltips displaying exact percentages on hover. The visualization uses D3 v7’s `d3.stack()` and `d3.scaleOrdinal()` for color encoding, with `d3.axisBottom` and `d3.scaleBand` for layout. Data comes from a CSV file containing genre-level rating proportions.
