This stacked bar chart shows the distribution of movie ratings across genres, with each bar representing a genre and segments showing the percentage of ratings in different categories. It uses D3.js v7 with an SVG rendering approach, where the data is processed through `d3.stack()` and mapped to horizontal bars. The chart employs `d3.scaleOrdinal()` for color coding and `d3.scaleBand()` for the y-axis layout. Interactive tooltips display exact percentages using `d3.select()` and event handlers, with the data loaded from a CSV file containing cereal information.
