This bar chart displays the populations of the ten most populous countries, based on 2018 estimates from the United Nations World Population Prospects. It uses d3.csv to load the data and d3.select to bind it to SVG rectangles, with each bar’s height reflecting the population value. The chart includes styled axes and labels via CSS, with the axis ticks and label text formatted using D3’s selection methods. Data values are converted from thousands to absolute numbers before rendering.
