This stacked bar chart shows the effect of genre on movie ratings, where each bar represents a genre and is segmented by rating level, with hover tooltips revealing precise percentages totaling 100%. Built with D3 v7, the visualization uses `d3.csv` to load data and `d3.stack` to compute stacked segments, rendering rectangles with `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis, while `d3.scaleOrdinal` applies color categories. Axes are generated via `d3.axisBottom` and `d3.axisLeft`, and SVG output is styled with external CSS fonts.
