SVG Fundamentals
This example demonstrates the fundamental building blocks of SVG rendering by displaying a single blue circle with a thick stroke. The visualization uses raw SVG elements defined directly in the HTML markup, with the circle's position, radius, and styling set through attributes. It relies on the browser's native SVG support via the `<circle>` element, with the `stroke` and `stroke-width` attributes controlling the outline. The code is a minimal static illustration with no interactivity or data binding, serving as a starting point for understanding SVG basics before incorporating React or D3.
