This example shows a minimal D3 page template that appends a new paragraph element to the body of an HTML document. The code uses the D3 selection method `d3.select("body").append("p")` to add the element, then sets its text content to "New paragraph!" via the `.text()` method. The page loads D3 from a local file and demonstrates the fundamental pattern of chaining D3 methods to manipulate the DOM. No data is involved; it is a bare-bones starting point for more complex visualizations.
