A red ball scales down and moves upward along a road drawn as a black trapezoidal path, creating the illusion of perspective. The animated transition uses D3.js v5's `transition.attr` to change the circle's radius and y-coordinate over two seconds. The SVG rendering includes a static road path defined with a template literal, while the ball's animation is the sole dynamic element. No data source is used; the example demonstrates basic D3 shape and transition APIs.
