This example demonstrates a minimal “Hello World” visualization, displaying a large, centered text message on a webpage. It showcases the basic setup of a D3.js project within VizHub, including how to structure files and import modules. The implementation uses D3 v5’s `select` function to target a specific HTML element by its ID and update its text content with a string exported from a separate ES6 module. Styling is applied via an external CSS file, setting the font size and alignment for the displayed message.
