This stylized bar chart displays the populations of the top 10 countries in 2020, sourced from the UN Population dataset. The data is loaded via `d3.csv` and rendered as SVG rectangles using React components, with `d3.scaleBand` for the categorical y-axis and `d3.scaleLinear` for the quantitative x-axis. Axis ticks are generated by `xScale.ticks()` with `d3.format` for SI-prefix labels, converting gigabytes to billions. The chart uses the Poppins font, teal marks, and a clean layout with custom margins and axis styling.
