This example displays a single black polyline with a drop shadow on a white background, rendered through an inline SVG. The path connects five coordinate points, creating a jagged, angular line across the 960×500 canvas. The code uses raw SVG elements—`path`, `rect`, and `filter` with `feDropShadow` effects—to achieve the visual result. No JavaScript libraries or data sources are involved; the styling comes from embedded CSS, and the graphic is entirely static.
