A scatter plot displays the population of the ten most populous countries, with circles positioned along a linear x-axis and a point-based y-axis. The visualization uses a vertical layout where each country is a row, and circle size is constant. Built with D3 v5, the code loads CSV data, scales population values using `scaleLinear`, and positions countries via `scalePoint`. It renders an SVG with axes, grid lines, and formatted tick labels (e.g., "1.42B") using `axisBottom` and `axisLeft`. The data comes from the included `data.csv` file.
