This example demonstrates fundamental SVG shapes rendered in a 500 by 500 pixel viewport, including circles, a rectangle, a line, and a path. It shows how basic geometry is drawn directly in HTML without JavaScript, using SVG elements such as `<circle>`, `<rect>`, `<line>`, and `<path>`. The code specifies attributes like `cx`, `cy`, `r`, `fill`, `stroke`, and `stroke-width` to control position, size, and styling. This serves as a minimal introduction to vector graphics in the browser, with no external libraries or data sources involved.
