This stacked bar chart shows how movie ratings are distributed across genres, with each bar segment representing the percentage of ratings within categories like below 5.0, 5.0–6.5, and above 8.5. The visualization uses d3.stack() to compute the stacked segments and d3.scaleOrdinal with custom colors to differentiate rating levels. Hover interactions trigger tooltips displaying exact percentages via d3.select and event handlers. The chart is rendered as SVG, using d3.axisBottom and d3.axisLeft for axes, with data loaded from a CSV file.
