This fork of the refactored bar chart displays the top 10 most populous countries from United Nations World Population Prospects 2019 data, using React and D3 v5. The visualization renders vertical bars whose widths encode population values, with axes generated through D3’s scaleBand and scaleLinear. SVG output is produced via React components, with the `AxisBottom`, `AxisLeft`, and `Marks` components building the chart’s structure and styling.
