Hello VizHub
This example demonstrates how the VizHub platform can be used to build a minimal interactive data-visualization page, showing static text rendered with large, centered styling. The visualization displays the message "Hello VizHub!" on a dark blue background with a custom Ubuntu font. The code uses D3 v5’s `select` method to target a `div` element and set its text content using a value imported from a separate ES6 module, `myMessage.js`. Styling is applied via an external CSS file that also imports a Google Font.
