This stacked bar chart visualizes the percentage distribution of IMDb rating levels across different movie genres, with each bar segmented into five rating bands from "below 5.0" to "above 8.5." Hovering over a segment displays a tooltip with the exact percentage for that rating level within the selected genre. The chart uses D3 v7 with a linear x-axis for percentages and an ordinal color scale for rating categories. The tooltip appears on mouseover events and updates position and content dynamically based on the hovered bar segment.
