This example renders primitive SVG shapes—a circle, a line, and a polyline path—inside an HTML page. It demonstrates direct SVG element creation via markup, with the circle centered at (50, 50) and the path drawn through explicit coordinate commands. No JavaScript libraries are used; the visualization relies solely on static SVG attributes like `cx`, `r`, `stroke`, and `d`. The rendering approach is pure SVG, with no data binding or animation.
