This stylized bar chart displays the population of the top 10 countries in 2019, using horizontal bars rendered as SVG rectangles within a React component. The chart employs D3 v7's `scaleBand` and `scaleLinear` for positioning, with data fetched from a CSV URL via `d3.csv`. The design includes a Poppins font, custom tick styling with a muted color palette, and tooltips showing population values formatted with `d3.format`.
