This bubble chart shows the correlation between vehicle weight, height, and length, with each car model represented by a circle positioned along the x-axis (weight) and y-axis (height). The bubble size encodes length, while the color differentiates the vehicle make, as shown by the accompanying legend. Hovering over a bubble reveals a tooltip with the model and exact measurements. The chart is built with D3 v7, using `d3.scaleLinear` for axes and bubble scaling, `d3.scaleOrdinal` with `d3.schemeCategory10` for color assignment, and SVG circles with mouseover events for interactive data display.
