This example displays the text messages “Hello VizHub!” and “Good” in large, centered text using D3.js. It demonstrates loading D3 v5 from UNPKG and using ES6 module imports, including a local module that exports the message strings. The code uses `select` from `d3` to target the `#message` and `#look` divs in the HTML and set their text content via the `text` method. Styling is applied through an external CSS file.
