This example presents a stacked horizontal bar chart that visualizes the distribution of grade percentage ranges (e.g., Below 60%, 60%-70%) across various academic subjects. Each bar is segmented by color-coded rating categories, with the width of each segment representing the proportion of ratings in that category. The visualization uses D3.js v7, employing `d3.stack()` for data restructuring, `d3.scaleBand()` for the categorical y-axis, and `d3.axisBottom()` for the continuous x-axis. Hovering over a segment reveals a tooltip with the exact percentage for that subject and rating band. Data comes from a CSV file.
