This chart uses a line chart to display the top ten countries by population, with circles marking each data point and a labeled axis. The visualization is built with D3 v5, using `select`, `csv`, `scaleLinear`, `scaleBand`, `axisLeft`, `axisBottom`, and custom formatting to convert values to billions. Population data is loaded from a CSV file and scaled, while the SVG rendering uses a transformed group element for the plotting area. The chart highlights the distribution of population sizes across the listed nations.
