This stacked bar chart visualizes the distribution of IMDb ratings across six movie genres, showing the proportion of films falling into five rating brackets from "below 5.0" to "above 8.5." Each bar represents a genre, segmented by rating category with distinct colors. The visualization uses d3.stack() to compute the stacked segments, d3.scaleBand for the categorical y-axis, and d3.scaleLinear for the percentage x-axis. Hover interactions highlight individual segments and display a tooltip with the exact percentage, computed from the pre-aggregated proportions in the CSV data.
