A stylized bar chart visualizes United Nations population data from 2019, rendering each country as a vertical rectangle within an SVG. The visualization maps the data using React components with D3 utilities, including `d3.csv` for data loading and `scaleBand` for positioning. The chart updates once the CSV data arrives, displaying a loading message beforehand. Each bar's height and position are computed directly from the dataset, creating a clean, minimal presentation of population figures across nations.
