This example shows a static SVG canvas containing basic geometric shapes—a circle, a stroked rectangle, a blue line, and a black path—placed at fixed coordinates. The page demonstrates a minimal D3 setup by using the `select` API from D3 version 6 to replace the body text with a greeting. The visual output is hand-coded in HTML, with no data binding or dynamic behavior, and rendering is done via inline SVG elements. The accompanying README references a YouTube tutorial for starting with D3.
