This stylized bar chart displays the populations of the ten most populous countries using data from the UN Population 2019 dataset. The visualization is built with React and rendered as SVG elements, with D3 v5 handling the scaling and formatting of the bars. The x-axis uses a linear scale with SI-formatted labels, while the y-axis employs a band scale for country names. The D3 `scaleBand` and `scaleLinear` APIs position the bars, styled with a teal fill and distinct tick marks, with tooltips showing the exact population values.
