This visualization displays the population of the top 10 most populous countries as circles arranged along a vertical axis, with circle positions encoding population magnitude on a linear scale. The chart uses D3.js v5 with SVG rendering, employing `scaleLinear` for the x-axis, `scalePoint` for country placement, and `axisBottom` with a tick formatter to abbreviate large numbers. Data comes from the 2018 UN World Population estimates, loaded via `csv()`, with populations multiplied by 1000 for accurate scaling. Grid lines and styled ticks enhance readability.
