This scatter plot displays the population of the top five most populous countries, using circular marks scaled along a linear x-axis. It ranks countries on a categorical y-axis using `d3.scalePoint`. The visualization is built with D3 v5, renders to SVG, and loads population data from a local CSV file. Axis ticks and titles are formatted using `d3.axisLeft`, `d3.axisBottom`, and `d3.format`.
