This example demonstrates a minimal D3.js v7 starter template. The page displays the text "Hello D3 version 7" in the body, then appends a div and an SVG element to the DOM. The code defines a small array of three point objects but does not render them as visible shapes, as the selection logic contains no data join or attributes. It uses D3’s selection and append methods, loading the library from unpkg.com, with the HTML and JavaScript split across separate files.
