A stacked bar chart displays the distribution of IMDb movie ratings across six genres, with each bar segmented into five rating brackets from “below 5.0” to “above 8.5.” The visualization uses d3.stack() to compute stacked segments and d3.scaleOrdinal for color encoding. Mouseover events reveal tooltips showing exact percentages, while d3.scaleBand and d3.scaleLinear position bars and axes. Data comes from an included CSV file, rendered as SVG with d3.v7.
