This example demonstrates the minimal setup required to begin using D3 version 6. It imports the `select` function from the `d3` module and uses it to target the `body` element, replacing its content with the text “Hello D3 version 6”. The accompanying README provides guidance on getting started with the library, and an embedded video offers additional instructional context. The code shows only this basic text insertion, with no data loading or advanced visualization features present. The rendering approach relies on direct DOM manipulation through D3’s selection API.
