A stacked horizontal bar chart visualizes the distribution of IMDb ratings across six film genres. Each bar shows the proportion of movies falling into five rating brackets, from below 5.0 to above 8.5, with Action clearly dominated by lower scores and Documentary leaning toward higher ratings. The code uses D3.js v7 to load data from a CSV file, stack the categories with `d3.stack()`, scale the bars with `d3.scaleLinear` and `d3.scaleBand`, and add interactive tooltips that display precise percentages on mouseover via SVG rectangles.
