This example displays a static SVG visualization of a patterned rectangular canvas with a subtle drop shadow and crisp edge rendering. The code embeds an SVG element directly in HTML, using filter operations like `feDropShadow` and `feGaussianBlur` to create depth, while a `pattern` element references an embedded image via `xlink:href`. It demonstrates fundamental SVG layout with explicit `width`, `height`, and `viewBox` attributes, alongside CSS-free styling through inline XML attributes. The example serves as a minimal introduction to SVG structure and compositing effects.
