This stacked bar chart visualizes the percentage distribution of IMDb ratings across different movie genres, showing the relative share of each rating band within each genre. Hovering over a segment displays its exact percentage via a tooltip. The chart uses D3.js v7 with `d3.stack()` to create the stacked segments, `d3.scaleBand()` and `d3.scaleLinear()` for axes, and `d3.scaleOrdinal()` for color coding. Data comes from a CSV file, rendered as SVG elements, with mouse events triggering opacity changes and tooltip updates.
