This example shows three red squares positioned diagonally across an SVG canvas, with a text label reading “this is my text” placed above them. The squares are rendered as SVG `<rect>` elements with explicit `x`, `y`, `width`, `height`, and `fill` attributes, while the label uses an SVG `<text>` element. The visualization is built with React and rendered via SVG, using plain HTML and CSS files where the stylesheet defines a class with a black fill. No interactive behavior or data binding is present; the graphic is purely static and hand-coded.
