This visualization displays the top 10 most populous countries using a horizontal bar chart rendered as SVG. The chart uses d3-scale’s `scaleBand` and `scaleLinear` to map country names and population values, with custom React components for the axes and marks. Data comes from the United Nations World Population Prospects 2019, loaded via d3.csv. The left axis lists country labels, while the bottom axis shows population ticks, with bars representing each country’s 2020 population.
