A minimal project graph demonstrates the use of D3 version 7 by rendering the text “Hello D3 version 7” in the browser. The example imports the `select` function from D3 and uses it to target the `body` element, setting its text content directly. The page’s style sets a large font size, while the code loads D3 from a CDN and executes from a separate bundle file. This serves as a basic verification that D3’s core selection API works correctly in a modern setup.
