This example demonstrates a bar chart of the top 10 most populous countries in 2020, using a margin convention to offset the chart area within the SVG canvas. The visualization is built with React and D3 v6, where D3 utilities load the UN population data from a CSV and compute the band scale and linear scale for the axes. The SVG rendering positions the grouped `<rect>` elements inside a translated `<g>` element, with margins applied to keep the chart clear of the canvas edges.
