This example displays a horizontal bar chart of World Bank population data for 31 countries, using the most recent year with available values. The React-based application loads the CSV data through a custom ES6 module that parses and filters the multi-row metadata headers. D3 v5’s `scaleBand` and `scaleLinear` map the country names and population values to SVG rectangles, while `axisLeft` and `axisBottom` render the axes. The chart demonstrates a modular architecture separating data loading, utility functions, and the bar chart component.
