This example displays a large, centered numeric message generated from a simple calculation, formatted and rendered using D3.js v5 and ES6 modules. It shows how VizHub supports importing local modules and D3 API functions, with the message derived from a mathematical expression and formatted using the `d3.format` method. The page uses a CSS import for the Ubuntu font and a dark blue background to make the text prominent. The code demonstrates basic DOM selection, module exports, and D3’s number formatting in a minimal setup.
