This stylized bar chart displays the population of the ten most populous countries from the United Nations World Population Prospects 2019 dataset. It uses React components to render SVG rectangles, with d3.scaleBand and d3.scaleLinear mapping countries and population values. Axes are built from custom React components calling xScale.ticks(), while a native SVG <title> element provides tooltips. The chart applies a teal fill, gray gridlines, and Roboto Condensed typography.
