This scatter plot displays the top 10 most populous countries, with each circle representing a nation’s population on a linear scale against country names on a categorical axis. The visualization uses D3 v5’s `scaleLinear` and `scalePoint` to map data, `axisBottom` and `axisLeft` for ticks and gridlines, and SVG circles for marks. Population values from data.csv are converted from strings to numbers and scaled to represent millions, with a formatted tick label replacing G with B for billions.
