This stacked bar chart shows how movie ratings are distributed across genres, with each bar representing the proportion of ratings falling into five categories from "below 5.0" to "above 8.5". Hovering over a segment reveals the exact percentage via a tooltip. The visualization uses d3.stack to compute the stacked segments, d3.scaleBand for the categorical y-axis, d3.scaleLinear for the percentage x-axis, and d3.axisBottom for ticks, rendering everything as SVG elements with a color-coded legend. The data comes from a CSV file containing genre and rating-level percentages.
