A pseudo line chart displays 33 randomly generated data points as a connected polyline that spans the full browser viewport. The example generates a path using raw SVG path commands, constructing the `d` attribute with a sequence of `L` (line-to) instructions. Rendered in red with rounded joins and caps at a 10-pixel stroke width, the chart fills the window by setting the SVG dimensions to the viewport size. The visualization does not use a plotting library, relying instead on direct SVG element creation through the Document API.
