A minimalist SVG composition demonstrates basic shape primitives and text labeling. Four black rectangles of varying widths and heights are arranged in a stepped layout against a white background, with the letters A through D positioned vertically along the left margin. The example uses raw SVG elements—`rect`, `path`, and `text`—rendered directly in HTML, with styling applied via the Fira Sans font family. No JavaScript libraries or data sources are involved; the visualization serves purely as a static reference for SVG structure and coordinate placement.
