This example displays a simple, large-format message, "Hello VizHub!", as a demonstration of basic D3.js integration within a VizHub activity. The visualization uses the D3 library (d3.v7) to select an HTML element with the ID `message` and set its text content. The rendering approach relies on a web page styled with Poppins font, where the text is centered with a large font size, showing a minimal workflow for combining D3 with local ES6 modules. The data source is a static string exported from a separate module, illustrating modular code structure.
