This stacked bar chart visualizes the percentage distribution of movie ratings across different genres, split into five rating levels from "Below 5.0" to "Above 8.5". The horizontal bars for each genre are subdivided into colored segments, with a legend identifying each rating category. The visualization is built with D3 v7, using `d3.scaleBand` and `d3.scaleLinear` for positioning, and an ordinal color scale for the rating segments. Data is loaded from a CSV file and rendered as SVG rectangles.
