A stacked bar chart displays the percentage distribution of five IMDb rating categories across six movie genres, showing how genre influences ratings. The chart uses SVG rendering with D3.js v7, employing `d3.scaleOrdinal` for colors, `d3.scaleLinear` for the x-axis percentage scale, and `d3.scaleBand` for the categorical y-axis. Hovering over bars triggers tooltips showing exact percentages, computed from the provided CSV data.
