This example by likhitha573 creates a stacked area chart from a CSV of user reviews, visualizing the distribution of review counts across five categories over an implied sequence of users. Built with D3.js v7, the chart uses `d3.area()` to render translucent, colored regions, with `d3.scaleOrdinal` for color and `d3.axisBottom`/`d3.axisLeft` for axes. The SVG output includes a title, axis labels, and a legend, with data loaded via `d3.tsv` from a GitHub gist.
