This horizontal stacked bar chart visualizes the proportional distribution of ratings across five categories (Technology, Science, Education, Healthcare, Finance) for a single metric. The stacked segments represent rating ranges from "Below 5.0" to "Above 8.5," with each bar scaled to 100% width. The visualization uses D3.js v7 with the `d3.stack()` and `d3.stackOffsetExpand` API to create normalized segments, color-coded via `d3.scaleOrdinal`. Labels display percentage values on segments wider than 40 pixels, and tooltips via SVG `<title>` elements provide exact percentages. Data is embedded directly in the HTML source.
