This scatter plot visualizes the top 10 most populous countries using circles positioned along a point scale for country names and a linear scale for population values from the 2018 UN World Population Prospects estimate. The code uses D3 v5 APIs including `csv`, `scaleLinear`, `scalePoint`, `axisLeft`, and `axisBottom` to render SVG elements, with tick formatting converting values to billions. Circle radii are fixed at 18 pixels, and gridlines extend across the plot area. The visualization features a title and axis labels, with data loaded from a local CSV file.
