This example shows simple SVG primitives—circles, lines, and paths—arranged on a blank canvas to demonstrate basic vector shapes. Overlapping red and green circles illustrate layering, while a red cubic Bézier curve and a black multi-segment path with rounded joins highlight path syntax. The code uses native SVG elements (circle, line, path) with inline fill and stroke attributes, rendered directly in the browser without any external JavaScript libraries. The SVG viewport is fixed at 960×900 pixels, with the body margin zeroed to avoid scrollbars.
