A scatter chart displays the populations of the ten most populous countries, with each country positioned along a categorical y-axis and population plotted on a linear x-axis. The visualization uses D3 v7 to load CSV data, apply `scaleLinear` and `scalePoint` for the axes, and render SVG circles. `axisBottom` and `axisLeft` generate ticks with custom formatting, while margin-based transforms position the chart elements.
