This example demonstrates a minimal D3.js visualization that displays a personalized greeting on a web page. The page renders the text “Hello Tyler!” centered on a dark blue background using the Ubuntu font. The code imports the `select` function from D3 and uses it to target the `#message` div, setting its text content with a message defined in a separate ES6 module. The styling is handled through CSS, including a Google Fonts import and large font sizing.
