This stacked bar chart shows the percentage distribution of five movie rating levels across six genres, revealing how genre impacts audience ratings. Each bar segment represents a rating category, with total percentage normalized to 100%. The visualization uses D3 v7 with SVG rendering and d3.stack() to create the stacked layout, d3.scaleOrdinal() for color mapping, and d3.scaleBand() for the categorical y-axis. Interactive tooltips appear on hover, displaying exact percentages via d3.select() and mouse event handlers. The data comes from a CSV file containing aggregated rating proportions for each genre.
