A bare HTML page that renders the text "Hello HTML" in the browser, centered and displayed at a very large font size of 13em. The example serves as a minimal starter template for HTML projects, using only inline CSS within a `<style>` tag to control the layout. It includes a separate `p.js` file that requires D3.js and appends a paragraph with the text "Test New Para!" to the body, demonstrating how to integrate D3 into a simple HTML document.
