svg fundamental
This example demonstrates fundamental SVG shapes using a single red circle positioned at coordinates (50, 50) with a radius of 50. The circle is rendered directly in the HTML document via inline SVG markup, without any JavaScript libraries or data sources. The example uses the native `circle` SVG element with `cx`, `cy`, `r`, and `fill` attributes, all set statically in the markup. The code illustrates the minimal structure required to display vector graphics in a web page, with a bare HTML file containing only an SVG container and its child shape.
