This example visualizes the distribution of IMDb movie ratings across six genres using a horizontal stacked bar chart. Each bar segment represents the proportion of ratings within a specific range (below 5.0, 5.0-6.5, 6.5-7.5, 7.5-8.5, above 8.5), with a sequential color scale distinguishing the categories. The chart is rendered as SVG using D3 v7, employing `d3.map`, `d3.stack`, `d3.scaleOrdinal`, and `d3.scaleBand` to construct the layout. Interactive tooltips display the exact percentage for each segment on hover, implemented via mouse event listeners.
