This visualization displays the top 10 most populous countries in 2020 as horizontal bars, with each bar’s length proportional to its population. The chart is rendered as an SVG using React components, with data loaded via D3’s `csv` utility. Margins are applied to position the inner group, while `scaleBand` and `scaleLinear` map country names and population values to pixel coordinates. The code also includes commented-out logic for generating pie arcs with `arc()` and `pie()`, though the active view uses simple rectangles.
