This bar chart displays population data for each country, with countries listed along the y-axis and population values on the x-axis. The visualization uses a linear scale for population and a band scale for countries, with custom tick formatting that converts large numbers into readable units like "Md" for millions. The chart is rendered using D3 v6 with SVG, pulling data from a CSV file sourced from the United Nations population data. Axes are customized by removing default domain lines and applying custom tick styling for a cleaner appearance.
