A scatter plot displays the population of the top 10 most populous countries, sourced from the 2018 United Nations World Population Prospects estimate. Using D3 v5, the code loads a CSV file, scales the population data on a linear x-axis, and plots points on an ordinal point-scale y-axis with SVG circles. It applies axisBottom and axisLeft to render gridlines and tick labels, formatted with d3.format, while styling titles and labels through CSS.
