This scatter plot displays the top 10 most populous countries using circular markers sized by population, with countries on the y-axis and population values on the x-axis. The visualization uses D3 v5’s `scaleLinear` and `scalePoint` for positioning, `axisLeft` and `axisBottom` for labeled axes, and SVG circles for the data points. Population data from the 2019 World Population Prospects is loaded via `d3.csv`, with values converted from thousands to raw counts. Axis labels and grid lines are styled with the included CSS.
