This stacked bar chart visualizes the distribution of movie ratings across six genres, using data from a CSV file. The chart shows the proportion of films falling into rating bands from "Below 5.0" to "Above 8.5" for each genre, with colors distinguishing the rating categories. Built with D3.js version 7, the visualization uses `d3.stack()` to create the stacked segments and `d3.scaleOrdinal` for color mapping. Hovering over any segment reveals an exact percentage via a tooltip, implemented with D3's mouseover events.
