Let's make a face with D3.js
This example renders a large-scale smiley face using D3.js and plain HTML/CSS. The page displays the word “Hello HTML” in a massive 13em font, while the accompanying JavaScript logs “Hello JavaScript!” to the browser console. The visualization relies on the DOM manipulation and styling capabilities of D3.js v3 within a React framework, though no interactive or data-driven elements are present. The code demonstrates a basic setup for integrating D3 with a web page, focusing on simple text rendering and developer-tool output rather than complex graphics or animations.
