This example shows a minimal HTML page that renders the text “Hi” in the browser, serving as a starting point for testing web-based visualizations. The page consists of a single `index.html` file containing a `<!doctype html>` document with a `<div>` element in the body. It uses no JavaScript libraries or APIs, only raw HTML and CSS defaults. The README includes an embedded YouTube video link. The rendering approach is static HTML without any data binding or dynamic updates.
