A bar-less scatterplot of the 10 most populous countries uses circles scaled by population on the x-axis and categorical country names on the y-axis. It renders with D3 v5’s `scaleLinear`, `scalePoint`, `axisLeft`, and `axisBottom` within an SVG. Data comes from a local `data.csv` file, parsed via `csv`. Axis grids use tick lines, and the chart includes a title and formatted population labels using `format('.3s')`.
