This stacked bar chart displays the proportion of IMDb ratings across five categorical groups, showing how category influences rating distributions. Each horizontal bar is segmented by rating bands from “below 5.0” to “above 8.5,” with colors assigned via `d3.scaleOrdinal`. The visualization uses `d3.stack` to compute stacked segments, `d3.axisBottom` for the percentage x-axis, and `d3.axisLeft` for category labels. Hovering over a segment triggers a tooltip that reveals the exact percentage for that rating level within the category, based on the provided data.csv.
