A stylized bar chart displays the top ten countries by 2020 population, using horizontal bars with rounded, teal fill and labeled axes. The data is loaded from a CSV of UN population figures via the `csv` function. The chart is built with React and rendered as SVG using D3 v5 scales: `scaleBand` for the categorical y-axis, `scaleLinear` for the numeric x-axis, and `scaleLinear` ticks for the bottom axis. Tooltips show formatted population values, with axis labels styled via Poppins font.
