This example shows a scatter plot of top countries by population, with points arranged along a vertical categorical axis and a horizontal value scale. It uses the D3.js library (version 7) to render the visualization as an SVG, with circles positioned using `d3.scaleLinear` for the x-axis and `d3.scalePoint` for the y-axis. Axis ticks are formatted with a custom function that abbreviates large numbers, and the underlying data comes from a CSV file containing country names and population figures.
