This example demonstrates the fundamental structure of an SVG line chart, plotting a single jagged path that moves across a fixed 620-by-288 coordinate system. The line is drawn using raw SVG markup inside an HTML page, with the `path` element’s `d` attribute defining six coordinate pairs connected by straight segments and a bold `stroke-width` of 11 pixels. No external libraries are used; the rendering relies entirely on native SVG syntax within the `index.html` file, styled by minimal CSS for text presentation.
