This example embeds a static SVG image of a data visualization directly into an HTML page, with D3 v7 loaded but not used for any dynamic rendering. The page displays the image via an SVG `<pattern>` referencing an embedded base64-encoded PNG, accompanied by a styled `<pre>` block titled "Data Visualization." The rendered content appears to be a pre-generated chart, though the code shows no data processing or interactive behavior. The visualization is presented as a fixed graphic within a Vue-powered page, demonstrating SVG embedding rather than D3-based chart construction.
