This visualization uses stacked horizontal bar charts to display the distribution of IMDb movie ratings across different genres. Each bar segment represents the percentage of movies within a specific rating range (below 5.0 through above 8.5), with the full bar showing the complete proportional breakdown for each genre. The chart is rendered as SVG using D3 v7, where `d3.scaleOrdinal` assigns colors to rating categories and `d3.stack()` computes the stacked segments. Mouse interactions trigger a tooltip that displays the exact percentage for each rating category. The data comes from a CSV file specifying genre and rating fractions.
