This example demonstrates a minimal web page that uses JavaScript with the D3 library to dynamically insert a personalized heading. It shows how to combine a custom JavaScript module, `epic-package`, with D3's `select` API to manipulate the DOM. The page renders "Welcome Back, Dan Heavern" by importing exported constants from the module and appending an `h1` element to the document body. The setup includes a minimal HTML structure and a `package.json` file specifying D3 version 7.4.4 as a dependency.
