This bar chart displays the population of the top 10 most populous countries, based on 2018 estimates from the United Nations World Population Prospects. Using D3 v5, the visualization employs `scaleLinear` and `scaleBand` to map population values and country names, with `axisLeft` and `axisBottom` rendering the axes. The SVG bars are generated from data loaded via `d3.csv`, with population values converted to thousands. The chart highlights relative population sizes across nations, presenting the data in ascending order along the y-axis.
