This example displays a simple welcome message, “Hello VizHub!”, using D3.js v6. The visualization renders the text in a large, centered font via a CSS style. The code imports the `select` function from D3 and an ES6 module that exports the message string. It then uses `select('#message').text(message)` to update the DOM element’s content, demonstrating basic D3 selection and data binding without any dynamic data or rendering.
