This stacked bar chart shows the distribution of IMDb movie ratings across six genres, with each bar segmented by rating level from below 5.0 to above 8.5. The visualization uses D3.js v7 with an SVG rendering, mapping genres along the y-axis and percentage along the x-axis. The code employs `d3.stack()` for stacked bar generation, `d3.scaleOrdinal()` for color encoding, and D3's axis APIs (`d3.axisBottom`, `d3.axisLeft`) for tick marks. Hovering reveals a custom tooltip displaying the exact percentage for each rating segment using `d3.format()`.
