This bar chart displays the populations of the ten most populous countries in 2018, with data from the United Nations World Population Prospects 2017. The chart uses D3 v5’s `csv` loader to parse the data, then applies `scaleLinear` for the population axis and `scaleBand` for the country axis, rendering bars as SVG rectangles. Axes are added via `axisLeft` and `axisBottom`, and each country’s population value is multiplied by 1,000 to reflect actual figures. The visualization is styled with steel-blue bars and a clean white background.
