This stylized bar chart displays the top 10 most populous countries, using horizontal bars to compare their 2020 population estimates from the UN Population dataset. The chart loads CSV data with the d3.csv utility and renders it through React, using d3.scaleBand and d3.scaleLinear for the axes and bar positioning. SVG elements comprise the visualization, with d3.format to abbreviate population values on the x-axis. The design employs a custom Poppins typeface and a teal color for the bars, while a native SVG tooltip shows precise population figures on hover.
