This stylized bar chart displays the population of the top 10 countries from the UN Population 2019 dataset. Orange rectangles, generated through React components, map each country’s population using d3.scaleBand and d3.scaleLinear. The SVG visualization includes labeled axes with tick formatting via d3.format, while CSS styles green tick text and an orange fill. Data is loaded asynchronously with d3.csv and React hooks, with hover tooltips providing formatted population values.
