This scatterplot shows World War II tank production, comparing tank weight against the number of units produced, with color encoding the country served. The visualization includes a delayed tooltip that displays tank details, with a caption indicating the two-second delay period. Built with D3 v7, the code loads CSV data from a GitHub gist, and uses d3.scaleLinear for quantitative axes, d3.scaleOrdinal with the Tableau10 scheme for categorical coloring, and d3.extent for domain calculations. The SVG chart renders points without brushing, linking, or animation.
