SVG fundamentals
This example demonstrates fundamental SVG rendering on an HTML page, showing two circles—one default black and one explicitly colored red—positioned at different coordinates. The code uses plain SVG elements within an inline `<svg>` tag, with the first circle relying on default styling and the second setting a `fill` attribute. It illustrates basic SVG shape creation without external libraries, serving as a minimal introduction to vector graphics in the browser. The rendering approach is purely declarative, using static markup for immediate visual output.
