A stacked horizontal bar chart shows the percentage distribution of IMDb ratings across six genres, using five rating brackets from below 5.0 to above 8.5. The code loads data from a CSV file and uses d3.stack, d3.scaleOrdinal, d3.scaleLinear, and d3.scaleBand to build the chart. Each segment displays a tooltip on mouseover that reports the exact percentage for that genre and rating bracket. The visualization uses SVG rendering with D3 v7.
