This bar chart displays the top 10 most populous countries based on 2018 United Nations population estimates, with population values multiplied by 1000. It emphasizes customizing D3 axes: the y-axis removes its domain and tick lines, while the x-axis uses a linear scale with custom tick formatting that removes gridlines and adds a labeled axis. Built with d3 v5, it uses scaleLinear, scaleBand, axisLeft, and axisBottom, rendered as SVG with a steel blue fill for bars.
