A stylized bar chart displays the top 10 countries by 2020 population, sourced from the UN_Population_2019.csv data. The visualization uses an SVG rendering with React and D3 v7, employing `scaleBand` and `scaleLinear` to map country names and population values. Horizontal bars include native tooltips via SVG `<title>` elements, with axes labeled using a custom SI format that converts gigabytes to billions. The chart applies a Poppins font and custom styling for a clean, minimal aesthetic.
