This stacked bar chart visualizes the distribution of IMDb ratings across six movie genres, with each bar segment representing the percentage of films within a given rating bracket. The chart uses `d3.stack()` and `d3.scaleBand()` to compose the segments, while `d3.scaleOrdinal()` assigns distinct colors. Tooltips reveal exact percentages on mouseover using `d3.select` and event handlers. Data comes from a CSV file, and the SVG rendering applies custom CSS styling for typography and hover effects.
