This example demonstrates basic SVG shape creation and styling using an HTML document with embedded SVG elements. It shows a black polyline and a blue filled path rendered on a 960x500 canvas, highlighting how SVG handles vector graphics through the `line` and `path` elements. The rendering approach relies on raw SVG markup with CSS applied through an external stylesheet that sets body margins to zero and hides overflow. This example uses the native SVG API via inline XML markup rather than JavaScript libraries, with shapes defined directly in the HTML structure.
