SVG Fundamentals
This example demonstrates the fundamental building blocks of SVG rendering through three colored circles positioned along a diagonal path. The visualization uses the SVG `circle` element with `cx`, `cy`, and `r` attributes, styled with `fill` colors of green, red, and blue. The code, embedded directly in an HTML page with inline CSS and JavaScript, creates a simple composition on a 1000x1000 canvas. It serves as a minimal starting point for understanding how React-based visualizations leverage SVG primitives for custom graphics.
