This example displays a fixed set of basic SVG shapes—a red circle, a green rectangle with a blue border, and a navy diagonal line—positioned statically on a 960 by 500 canvas. The markup originates from an `index.html` file that directly embeds SVG elements without JavaScript data binding or interaction. It demonstrates a minimal rendering approach using inline SVG, with styling applied through a simple CSS rule for centered text, though no text is currently shown. The illustration serves as a bare-bones starting point for React-based projects, highlighting core shape primitives.
