This stacked bar chart shows the distribution of IMDb movie ratings across five genres, with each bar representing 100% of ratings for that genre, broken down into five rating categories from below 5.0 to above 8.5. Using d3.v7, the visualization employs `d3.stack()` to create the stacked segments, `d3.scaleOrdinal()` for color encoding, and `d3.axisBottom()` and `d3.axisLeft()` for axes. Hovering over a bar segment triggers a tooltip displaying the precise percentage via a `mouseover` event handler. The data comes from a CSV file containing genre and rating percentage columns.
