A scatter plot displays the population of the top 10 most populous countries, using 2018 estimates from the United Nations World Population Prospects 2019. Each circle’s vertical position corresponds to a country, while its horizontal position reflects population size on a linear scale. The visualization uses D3 v5’s `csv` loader, `scaleLinear`, `scalePoint`, `axisLeft`, and `axisBottom` to render SVG circles and gridlines, with tick labels formatted in billions.
