This stacked bar chart shows the percentage distribution of five rating brackets across six movie genres, revealing that documentaries and dramas skew toward higher ratings while action films cluster in the lowest tier. Each genre’s bar is divided into colored segments corresponding to rating levels, with hover tooltips displaying precise percentages that sum to 100%. Built with D3.js, the visualization uses `d3.csv` to load the dataset, `d3.scaleBand` for x-axis positioning, `d3.scaleOrdinal` for categorical color mapping, and `d3.stack` to compute the stacked layout. Axis labels and tick formatting are customized via D3’s SVG rendering, with tooltips implemented through mouse event handlers.
