A bare HTML page renders a single SVG element with no content, demonstrating the minimal structure for a visualization. The page loads no external libraries or scripts, relying solely on the browser’s native SVG namespace to provide an empty canvas. The code includes no data, no drawing functions, and no interaction, serving purely as a starting template for future D3 or other SVG-based work. The iframe in the README points to a YouTube video, but the visualization itself shows nothing beyond the empty SVG tag.
