This scatter plot displays the populations of the world’s most populous countries in 2020, with each circle positioned along a categorical y-axis for country names and a linear x-axis for population counts. The visualization uses D3 v5 with SVG rendering, employing `scaleLinear` for the x-axis, `scalePoint` for the y-axis, and `axisBottom` and `axisLeft` for ticks. Data is loaded from a CSV via `d3.csv`, and population values are formatted using `d3.format` to abbreviate large numbers.
