A scatter plot displays the populations of thirteen countries, with each circle animating horizontally from zero to its population value along a linear scale. A point scale positions the country labels on the vertical axis, while gridlines extend from the axes. The visualization uses D3 v5’s `scaleLinear`, `scalePoint`, `axisLeft`, `axisBottom`, and `transition.attr` to animate the circles. Population data is loaded from a CSV file using `csv`, then converted to numbers before rendering as SVG circles.
