A minimal "Hello VizHub" template demonstrates a bare-bones HTML document that renders the text "hello" in a preformatted block. The example loads a stylesheet and an external script, while the JavaScript file defines a message variable but does not yet attach it to the page. The code uses standard DOM APIs such as `document.getElementById`, though the targeted element is not present in the markup. This serves as a starting point for building interactive visualizations in the VizHub environment.
