This scatter plot displays the populations of the ten most populous countries, with countries on the y-axis and population on the x-axis. Using D3 v5, it employs `scaleLinear` and `scalePoint` to map the data, `axisBottom` and `axisLeft` for labeled axes, and SVG circles for points. The code loads data from a CSV file and formats x-axis tick labels from millions to billions using the `format` function.
