This bar chart displays the populations of the ten most populous countries, based on 2018 estimates from the United Nations World Population Prospects. Using d3.scaleBand for the categorical y-axis and d3.scaleLinear for the numerical x-axis, it customizes both axes by removing domain lines and applying tick formatting with d3.format. The visual is rendered as SVG, with gridlines drawn from x-axis ticks and a clear title and axis label.
