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." Each genre’s row represents the percentage proportion of movies falling into each rating band, normalized to sum to one. Built with D3 v7, the visualization uses `d3.stack()` to compute the stacked series, `d3.scaleLinear()` for the percentage axis, `d3.scaleBand()` for genre categories, and `d3.scaleOrdinal()` with a five-color palette. Interactive tooltips display the exact percentage per category on hover, while SVG rendering handles all graphical output.
