This example demonstrates the simplest possible D3 starter project: a blank HTML page that uses D3 version 7 to display the text “Hello D3 version 7” in the center of the body at a huge font size. The code imports the `select` function from the D3 library and applies it to the `body` element, setting its text content. The page loads D3 from a CDN and renders the message via a separate `bundle.js` file.
