This example renders a minimal HTML page with embedded CSS and JavaScript, demonstrating the fundamental structure of a web-based visualization. The code defines an empty HTML document with a style block and a script tag, providing a blank canvas for adding custom visualizations. It uses plain DOM elements and JavaScript without any external libraries or frameworks, highlighting the bare essentials needed to build a data visualization. The page includes a connection to a React Starter example, though it currently contains no rendering logic or data processing.
