SVG Fundamentals
This example demonstrates basic SVG shapes rendered directly in HTML, showing circles, a rectangle, and a line with various colors and stroke settings. The code uses native SVG elements such as `<circle>`, `<rect>`, and `<line>`, each with attributes like `cx`, `cy`, `r`, `width`, `height`, `stroke`, and `stroke-width`. No JavaScript libraries or data sources are involved; the rendering relies entirely on SVG markup within a fixed 960×500 canvas. The visual output highlights fundamental shape primitives and styling properties without interaction or animation.
