This scatter plot displays the 2018 population estimates for the top 10 most populous countries, using circles positioned along a horizontal population axis and a vertical country axis. The chart is rendered as an SVG using D3 v6, with a linear scale for population and a point scale for country categories. The code loads data from a CSV file, converts population strings to numbers, and uses `scaleLinear`, `scalePoint`, `axisBottom`, and `axisLeft` to construct the visualization. Axis tick formatting converts large numbers into abbreviated units like "B" for billions.
