This stylized bar chart visualizes the top ten countries by population according to the United Nations World Population Prospects 2019. It presents categorical data horizontally, with countries along the y-axis and population values along the x-axis. The visualization uses D3 v7 within a React framework, rendering SVG marks and axes. D3’s `scaleBand` and `scaleLinear` position the bars, while `format(".2s")` converts tick labels from gigabytes to billions. A Poppins font and muted custom color scheme define the stylized aesthetic.
