A stacked horizontal bar chart displays the percentage distribution of IMDb ratings across six movie genres, with each bar segmented into five rating categories from below 5.0 to above 8.5. The visualization uses d3.stack to generate the stacked series and d3.scaleOrdinal for color mapping, rendering SVG rectangles with tooltips that show exact percentages on mouseover. Data comes from a CSV file, and axes are created using d3.axisBottom and d3.axisLeft.
