This example demonstrates a minimal D3 version 7 setup where the text "Hello" is rendered directly into the page body using the `select` method from the D3 API. The code also initializes a range of ten numbers and filters for even values through array methods, though this computed result is only logged to the console rather than displayed. The visualization relies on D3’s DOM selection and text-insertion functions, with all styling handled via CSS. The page itself is a blank canvas centered around large text, showing the simplest integration of D3’s core selection and manipulation capabilities.
