svg fu ndamentals
This example demonstrates a single dark ellipse rendered on a large SVG canvas, occupying the center of the viewport. The code defines the shape directly in markup using the `<ellipse>` element with explicit `cx`, `cy`, `rx`, and `ry` attributes, and applies a solid `#1E1E1E` fill. No external libraries or JavaScript are involved; the visualization relies solely on native SVG rendering within a static HTML page.
