A scatter plot displays the ten most populous countries, with population on the x-axis and country names on the y-axis, using circles to represent each data point. The visualization loads CSV data and uses d3.csv, d3.scaleLinear, d3.scalePoint, d3.axisBottom, and d3.axisLeft to render the chart in SVG. Population values are formatted in billions using d3.format. The chart includes a title, axis labels, and grid lines created through tick sizing.
