This example visualizes IMDb movie ratings by genre as a stacked horizontal bar chart, showing the proportion of titles falling into five rating brackets from below 5.0 to above 8.5. The chart uses d3.stack with d3.scaleOrdinal for color encoding and d3.scaleBand for the categorical genre axis, rendering SVG rectangles per segment. Interactive tooltips display exact percentages on hover using d3.select and mouse event handlers. Data comes from a CSV file with pre-aggregated genre-wise rating distributions.
