This example demonstrates how to create a minimal D3.js visualization within the VizHub environment. It renders the text “Hello VizHub!” to a web page by selecting a `div` element with `d3.select` and setting its text content. The code imports the `select` function directly from the D3 v5 library and also uses an ES6 module, `myMessage.js`, to supply the string. Styling comes from an external CSS file, with the message displayed in large, centered type.
