This example displays ten colored rectangles that can be dragged around an SVG canvas. The shapes are randomly positioned and sized using D3’s `d3.range` and `Math.random()`, with each rectangle filled via the `d3.schemePastel1` color scheme. The interactive drag behavior is implemented with `d3.drag()`, which updates the x and y attributes in the `dragged` event and raises the selected element to the front on drag start.
