This example displays a plain-text message, "Hello you!", centered on a light blue background. The visualization demonstrates a minimal data-report setup using D3 v5 and a custom module. It imports a string from `My_message.js` and the `select` function from D3, then uses `select('#message').text(message)` to inject the text into the HTML element. The page’s styling comes from `styles.css`, applying the LightBlue background and white text.
