This example displays the top ten most populous countries as circles, using a bar-chart-like layout where circle position encodes population on a linear scale and country on a point scale. The chart uses D3 v5’s `scaleLinear`, `scalePoint`, `axisBottom`, and `axisLeft` to construct the axes and `selectAll`/`append` to render SVG circles. Data originates from a UN report, loaded from a CSV file.
