Hello World
This example renders the text “Hello World!” in a large, lime-green, centered display using D3.js v5. It imports the `select` function from D3 to target the `#message` div and sets its content from a locally imported ES6 module (`myMessage.js`). The styling comes from an external `styles.css` file, while the HTML structure is minimal. The visualization simply demonstrates a basic D3-driven text output, with no interactive or animated behavior present.
