This visualization displays EV sales data by brand and year. It loads CSV data from a GitHub gist and presents a summary table of all records alongside an SVG bar chart showing total units sold for Tesla, Nissan, and Chevrolet. The bar chart uses D3 v7 within a React framework, with axes, gridlines, and a title rendered as scalable vector graphics. Population-by-country data is also loaded separately, with a bar chart showing the top countries by population.
