This example demonstrates a simple data-loading workflow using D3.js version 5 and ES6 modules. It displays a static "Hello VizHub!" message styled with a large Ubuntu font on a dark blue background. The code imports the `select` and `csv` functions from D3, then fetches `data.csv` asynchronously and logs the parsed population data to the browser console. No visual representation of the data is rendered—only the message and console output are shown.
