Built with D3.js v7, this example draws a cartoon truck as an SVG composition of rectangles and circles, including a red body, blue cabin, white window, yellow backlight, and two black wheels. Clicking the truck triggers a two-second `transition` that translates the entire group horizontally across the canvas, while the wheels rotate 720 degrees via `transition.attrTween` and `d3.interpolateString`. The wheels spin independently during the movement, and repeated clicks restart the animation, making the truck advance slowly across the gray-bordered SVG stage. It demonstrates reusable transition chaining on grouped SVG elements.
