This example demonstrates a minimal D3.js visualization that renders a static text message centered on a webpage. The code imports the `select` function from D3 to target the HTML element with the id `message`, then sets its text content using a string imported from a local ES6 module, `myMessage.js`. The styling is handled entirely through an external CSS file, which sets the font size and alignment. The visualization relies on D3 v5 loaded via UNPKG, and the rendering approach is a simple DOM text update rather than a graphical chart.
