This example shows a single circle positioned inside an SVG container. The circle is placed at coordinates (100, 100) with a radius of 20 and a fill referencing a gradient defined as `#land1-gradient`. The page relies on plain HTML structure without any JavaScript logic or CSS styling rules in the provided files. It demonstrates the minimal setup for rendering static SVG shapes in a web page, using the SVG `<circle>` element and the `fill` attribute with a gradient reference.
