This stacked bar chart visualizes the percentage of five rating levels for different movies, showing how genre impacts audience ratings. Each movie’s bar is segmented by rating categories, with hover tooltips revealing precise percentages. The visualization uses D3 v7’s `d3.stack()` and `d3.scaleOrdinal()` for color encoding, with `d3.scaleBand()` for the y-axis and `d3.scaleLinear()` for the x-axis. Data comes from a local CSV file, rendered as SVG rectangles with interactive mouse events for tooltip display.
