This example shows a horizontal bar chart of population data for the top 10 countries in 2020, using React state management with hooks to load and render the data. The visualization displays country names on the y-axis and population values on the x-axis, with formatted tick labels converting large numbers to abbreviations like “1.5B.” The code leverages D3 v5 APIs including `scaleBand`, `scaleLinear`, `csv`, and `format`, while rendering SVG elements through React components. Styling uses a custom Poppins font and muted colors, with data sourced from a CSV of the UN Population 2019 dataset.
