A stacked bar chart visualizes the distribution of IMDb movie ratings, from below 5.0 to above 8.5, across six genres. Each horizontal bar represents a genre and is segmented by rating level, showing the proportional percentage of movies within each category. The chart uses d3.scaleOrdinal for color mapping and d3.stack to create the stacked segments. Hovering over a bar segment displays a tooltip with the exact percentage for that rating level, while a legend identifies each rating category. The data is loaded from a CSV file, and the visualization is rendered as an SVG.
