This empty D3 starter template displays a blank canvas, providing a foundational structure for building custom data visualizations. The code includes a minimal HTML page with a script tag referencing D3.js version 4.5.0, along with placeholder JavaScript and CSS files. The `index.js` file only logs "hello world" to the console, while `styles.css` contains styling for a `.message` class with large font size and centered text alignment. The example demonstrates a bare-bones project setup, ready for users to insert their own D3 code and data.
