This bar chart displays the population of the top 10 most populous countries, based on 2018 UN estimates from the World Population Prospects. The data is loaded from a CSV file and mapped to the chart’s axes using D3’s `scaleLinear` and `scaleBand` functions. The visualization is rendered as an SVG, with countries on the y-axis and population on the x-axis. The chart uses D3 v5 and the `select`, `csv`, `axisLeft`, and `axisBottom` APIs to build the final graphic.
