This bar chart displays the population of the top 10 most populous countries, using 2018 estimates from the United Nations World Population Prospects. The visualization uses D3 v5 with SVG rendering, employing `scaleLinear` for the x-axis and `scaleBand` for the y-axis. The code customizes axes with `axisLeft` and `axisBottom`, and loads data from a CSV file via `csv`. Each bar’s width is proportional to population, with values multiplied by 1000 in the data preprocessing step.
