A stacked horizontal bar chart shows the distribution of IMDb ratings across six film genres, with each bar divided into five rating brackets from below 5.0 to above 8.5. The chart reads percentages from a CSV file and renders them as proportional colored segments using D3 v7’s `d3.stack`, `scaleOrdinal`, `scaleLinear`, and `scaleBand` APIs. Mouseover interactions trigger tooltips displaying the exact percentage for each genre-rating combination. The visualization uses an SVG output with custom margins, axis labels, and a legend positioned to the right.
