Fork of Refactored Bar Chart
This visualization displays a horizontal bar chart of the top 10 most populous countries from the United Nations World Population Prospects 2019 dataset. Each bar represents a country’s 2020 population estimate, rendered as a colored rectangle. The chart uses React for component structure and D3 v5 functions like `scaleBand` and `scaleLinear` to map data to SVG coordinates, with custom `AxisBottom` and `AxisLeft` components providing tick marks and labels.
