This stacked bar chart shows the distribution of IMDb movie ratings across six genres, with each bar divided into five rating categories from "below 5.0" to "above 8.5" as proportions of total films. The visualization uses d3.stack() to compute the stacked segments, d3.scaleBand() for the genre categories, and d3.scaleLinear() for the percentage axis on a logarithmic-free linear scale. Hovering over any segment reveals a tooltip displaying the exact percentage for that genre and rating range. The data comes from a CSV file containing genre-wise rating proportions, rendered as SVG rectangles with a color scale distinguishing each rating band.
