This example shows a collection of concentric circles and lines rendered on a large SVG canvas using plain JavaScript within an HTML page. It uses the SVG API directly, with elements like `<circle>` and `<line>` to create layered color patterns and a target-like composition. The rendering approach relies on static SVG markup, with no dynamic data or interaction. The code includes a basic CSS style for text and a commented-out rectangle, while the main visual elements are defined inline in the document body.
