This example presents a horizontal bar chart of 2020 population estimates for ten countries, sourced from the United Nations population data for 2019. The visualization uses React to render SVG elements, with D3 scales handling the spatial mapping. Unique React keys, derived from country names and tick values, manage element updates. The chart displays a grid of x-axis ticks and labeled bars, with axes and labels generated through D3’s scaleBand and scaleLinear APIs.
