This example demonstrates basic SVG shape rendering within a React-based visualization gallery. It displays a red circle and a rectangle on a 960 by 500 canvas, using plain SVG elements defined directly in the HTML. The styles.css file applies a global reset and adds a `.highlighted` class that turns text red, though the shapes themselves use default styling. The implementation relies on core SVG APIs (`circle` and `rect`) rather than higher-level libraries like d3, showcasing minimal markup for static geometric figures.
