A minimal example introduces the VizHub environment with a static SVG circle on a dark background. It demonstrates an ES6 module exporting a text message, which D3.js selects and applies to a page element using the `select` function. The SVG markup is hand-authored in the HTML file, and the styling uses external Google Fonts. This example showcases basic project structure and integration of D3 v5 with custom JavaScript modules for simple visualization output.
