A generative geometric composition displays a set of nested rectangles arranged diagonally across a 960-by-500 SVG canvas. The rectangles scale and position according to a computed mathematical sequence, while each stroke width is randomized. Built with React and ReactDOM, the code maps an array of 50 values to SVG `<rect>` elements, applying a drop shadow filter via `<feDropShadow>`. The rendering uses JSX to declare the SVG structure, with no interactive or animated behavior present.
