This scatter plot displays the estimated 2015 populations of four transboundary river basins in Africa, based on data from the Africa Union. The x-axis uses a linear scale for population values with tick labels formatted in billions, while the y-axis uses a point scale for basin names. Implemented with D3 v5, the visualization renders SVG circles, axes, and labels using `d3.scaleLinear`, `d3.scalePoint`, `d3.axisBottom`, and `d3.axisLeft`. Grid lines extend across the plot, and the data is loaded from a CSV file.
