A D3 Scatter Plot displays a single "Hello D3" message centered on a blank page, serving as a minimal starter example. The visualization uses the D3 v7 selection API via `d3.select` to target the body element and sets its text content with `.text('Hello D3')`. Styled with CSS for centered alignment and a large font size, the example demonstrates the basic setup of an HTML page with an import map loading D3 as an ES module. No dataset or rendering primitives are involved; it focuses purely on initializing a D3 environment.
