This visualization shows the distribution of IMDb movie ratings across seven genres, using a stacked horizontal bar chart where each bar segment represents the proportion of movies falling into five rating categories from "below 5.0" to "above 8.5." The chart uses D3 v7's `d3.stack()` and `d3.scaleOrdinal` with a custom color palette, rendering as SVG with axes from `d3.axisBottom` and `d3.axisLeft`. Interactive tooltips display exact percentages on mouseover, and the data comes from a CSV file with genre-proportion pairs.
