Four plain rectangles of decreasing height stand in a row, approximating a bar chart through minimal geometric forms. The code uses raw SVG `rect` elements within an HTML document, with no data-binding or charting library. Each rectangle is manually positioned using fixed `x`, `y`, `width`, and `height` attributes, creating a static, composition-like visualization that echoes Sol LeWitt's instructional art. The page sets the body margin to zero and hides overflow, while the SVG canvas is sized at 960 by 500 pixels.
