SVG starter
This example demonstrates fundamental SVG shape drawing and grouping within a static HTML page. It displays circles, rectangles, and a line, each with explicit position, size, and color attributes. The code uses raw SVG elements like `<circle>`, `<rect>`, and `<line>`, and applies a `<g>` element with a transform to shift a group of shapes and add stroke styling. The source is a single `index.html` file that renders directly to SVG.
