This interactive bar chart displays the ten most populous countries in the world, using horizontal bars to compare their 2020 population estimates. Built with React and D3 v5, the visualization renders as an SVG, with scales and axes created through `d3.scaleBand` and `d3.scaleLinear`. Data is loaded from a CSV file of the UN World Population Prospects 2019, with population values formatted into billions. The chart includes labeled axes, tick marks, and tooltips that appear on hover for each bar.
