This example demonstrates a minimal, text-based visualization: a web page that renders the words "Hello version 7" in enormous type. It serves as a basic starter template for D3 version 7, showing how to set up an HTML canvas and begin scripting. The code uses D3’s `select` method to target the document’s body element and then applies the `text` method to insert the string. The visualization relies on D3’s standard DOM manipulation API rather than any data source or charting technique, focusing purely on the initial setup for a new project.
