This stacked bar chart shows the distribution of IMDb rating levels across six movie genres, revealing that documentaries and dramas tend to receive higher ratings while action films skew toward lower scores. Each horizontal bar is segmented into five rating categories using `d3.stack()` and `d3.scaleOrdinal` with a categorical color scale. Mouse hover interactions trigger tooltips displaying exact percentages via `d3.select` and event handlers. The visualization is rendered as SVG using D3 v7, with data loaded from a CSV file and axes formatted using `d3.axisBottom` and `d3.axisLeft`.
