This stylized bar chart displays the top 10 most populous countries using United Nations World Population Prospects 2019 data. The visualization uses React with D3 v5, employing `scaleBand` for the categorical y-axis and `scaleLinear` for the population x-axis. SVG rectangles render the bars, with axis components built from custom React functions that map ticks using `d3.format` to abbreviate population values. The Poppins font and teal color scheme give the chart its distinctive stylized appearance.
