This bar chart visualization displays the 2022 population data of countries classified as RICH, sourced from a CSV file of COVID-era data. The React-based app uses D3 v5 APIs including `scaleBand`, `scaleLinear`, and `csv` to load and render horizontal bars as SVG rectangles. Axes are drawn with `axisLeft` and `axisBottom`-style manual tick generation, with purple gridlines along the x-axis. The chart shows only the first eleven countries from the dataset, with each bar’s length proportional to its population value.
