This stylised bar chart displays the top 10 countries by population in 2020, using a horizontal bar layout with a clean, minimal aesthetic. Population values are formatted with a custom tick formatter that converts large numbers to billions with a 'Bil' suffix. Built with React and D3 v5, the visualization uses `scaleBand` for the categorical y-axis, `scaleLinear` for the quantitative x-axis, and SVG `<rect>` elements for bars, with native `<title>` elements providing hover tooltips. The chart is styled with a Poppins font and a teal color scheme.
