This example demonstrates the basics of JavaScript syntax and variables, contained entirely within an HTML page. The SVG element provides an empty rendering surface, while the script includes commented-out code showing console logging, arithmetic, const and let variable assignment, object property mutation, and a for loop. The visualization uses no external libraries or data sources, relying solely on vanilla JavaScript to illustrate fundamental programming concepts. The code is fully commented out, so the page renders as a blank SVG without any visible output or interactive behavior.
