This visualization displays the top 10 most populous countries as a series of horizontal bars with no axes, using data from the United Nations World Population Prospects 2019. Each rectangle’s width encodes the country’s 2020 population via `d3.scaleLinear`, while its vertical position relies on `d3.scaleBand`. The React component loads the CSV with `d3.csv`, slices the first ten rows, and renders SVG rectangles. The chart intentionally omits labels and scales, presenting a minimal, decontextualized view of population ranking.
