This horizontal stacked bar chart visualizes the proportional distribution of movie ratings across genres, with each bar divided into colored segments for action, comedy, drama, thriller, and horror. Built with D3 v7 and rendered as SVG, the chart uses d3.stack(), d3.scaleBand(), and d3.scaleLinear() to position segments, while d3.axisBottom with gridlines and custom tooltips display exact percentages on hover. Data comes from a static CSV file loaded locally.
