This ordinal scatter plot shows the population of the top 10 most populous countries as circles positioned along a categorical y-axis, with a linear x-axis for population values. The chart uses `d3.scalePoint` for the ordinal country scale and `d3.scaleLinear` for population, with circle radius fixed at 18. Axes are generated via `d3.axisLeft` and `d3.axisBottom`, while population labels use `d3.format` with custom tick formatting to abbreviate values. Data comes from the 2017 United Nations World Population Prospects estimate, loaded from a CSV file with `d3.csv`.
