This ordinal scatter plot displays the populations of the top 10 most populous countries from the 2018 United Nations World Population Prospects estimate, with countries arranged on the y-axis and population values on the x-axis. Using D3 v5, the code employs `scalePoint` for the categorical country positions, `scaleLinear` for the numeric population scale, and SVG circles to mark each data point. The chart includes a formatted x-axis that abbreviates large numbers using the `format` function, and grid lines are drawn via axis tick sizes.
