This visualization displays the relationships among World War II tanks by plotting each tank's weight on the x-axis, production amount on the y-axis, and horsepower as the visual size of the circular mark. Country served is encoded through color. The page summarizes the dataset with row counts, field names, and the range, mean, and median of tank weights. Built using D3.js v7 with SVG rendering, the chart leverages `d3.csv` for data loading, `d3.scaleLinear` for axes, `d3.scaleOrdinal` for categorical color mapping, and `d3.extent` with `d3.mean` and `d3.median` for statistical summaries.
