This example visualizes the distribution of IMDb movie ratings across different genres, using a 100% stacked horizontal bar chart. Each genre (Documentary, Drama, Comedy, etc.) is represented by a bar composed of segments corresponding to rating categories (below 5.0 to above 8.5), with segment lengths proportional to the percentage of movies in that rating band. Rendered as an SVG using D3 v7, the chart employs `d3.stack()` to compute the stacked segments, `d3.scaleBand` for the y-axis genres, and `d3.scaleLinear` for the x-axis percentages. A tooltip displays the exact percentage when hovering over a segment, and the data is loaded from `data.csv`.
