A stacked bar chart visualizes the percentage distribution of IMDb rating categories within each movie genre, using horizontally segmented bars to show proportions that total 100%. Hovering over any segment reveals a tooltip displaying the exact percentage for that rating level and genre. The chart is built with D3 v7, using `d3.stack()` for data stacking, `d3.scaleBand()` and `d3.scaleLinear()` for axes, and `d3.scaleOrdinal()` for color encoding. Data comes from a CSV file containing genre and rating percentage columns, rendered as SVG with interactive mouse event handlers.
