This stacked bar chart visualizes the percentage distribution of movie ratings across different genres, with each bar segmented by rating level. The chart uses a horizontal layout where genre categories are on the y-axis and percentages on the x-axis, with hover interactions displaying exact values via tooltips. The visualization is built with D3.js v7, using `d3.scaleOrdinal` for color mapping, `d3.scaleBand` for y-axis positioning, and `d3.axisBottom` for the x-axis. Data is processed through `d3.stack` to create the stacked segments, and SVG is used for rendering.
