This stacked bar chart visualizes the distribution of five personality traits—Sarcastic, Funny, Stylish, Moody, and Attractive—among six Friends characters. Each bar represents a character, with segments proportionally sized to sum to 100% per character. Hovering over a segment triggers a tooltip displaying the precise percentage. The visualization uses D3 v7 with `d3.stack()`, `d3.scaleBand()`, and `d3.scaleLinear()` to compute and render the stacked layout as SVG rectangles, with a custom color scale for each trait.
