A small square rotates around a circular path within an SVG canvas, moving at a constant speed. The rotation is driven by a JavaScript loop that updates the rectangle's transform at regular intervals. The code uses the SVG `createSVGTransform` API and `setTranslate` to reposition the element, with `setTimeout` scheduling 100 incremental steps along the circle. The result is a simple, self-contained animation rendered in SVG, with no external libraries beyond plain JavaScript.
