This stacked bar chart compares the percentage distribution of ratings across six categories—Technology, Finance, Healthcare, Education, Sports, and Entertainment—using horizontal bars. Each bar is segmented into five rating bands, from "below 4.0" to "above 9,” with a legend in the right margin. The visualization uses D3 v7's `d3.stack()` to aggregate the data and `d3.scaleOrdinal()` for color mapping. An SVG renders the chart, while mouseover events display a tooltip showing the exact percentage for each segment. The data is loaded from a local CSV file.
