This stacked bar chart visualizes the percentage distribution of IMDb movie ratings across five genres, with each bar segment representing a rating level from below 5.0 to above 8.5. The chart reveals how genre influences ratings, showing that documentaries achieve higher percentages of top ratings while action films skew toward lower scores. Built with D3 v7 and rendered as SVG, the visualization uses `d3.stack()` to create the stacked segments and `d3.scaleOrdinal` for color encoding. Interactive tooltips appear on mouseover, displaying precise percentages for each rating level within a genre, calculated from the provided CSV data.
