Hello VizHub!
This example demonstrates VizHub’s basic workflow by rendering the text “Hello VizHub!” in a large, centered Ubuntu font on a dark background. It shows how a D3.js v5 selection, using `select('#message')`, sets the text content of a `div` element. The message originates from an ES6 module (`myMessage.js`) that exports a constant string, which is imported in `index.js`. The page structure is defined in `index.html`, and styling relies on a Google Fonts import and a small CSS ruleset.
