A scatter plot displays the population of the top nine most populous countries using 2019 United Nations estimates, with each country represented by a circle positioned along linear population and point-based country scales. The visualization is rendered as SVG using D3 v5, leveraging `d3.csv` for data loading, `d3.scaleLinear` and `d3.scalePoint` for axes, and `d3.axisBottom`/`d3.axisLeft` with formatted tick labels. Grid lines created by axis ticks extend across the plot, highlighting population magnitudes for countries like China and India.
