This example presents a nearly blank SVG canvas as a starting point for learning JavaScript. The page embeds a `<script>` tag within the SVG element, where console logging and basic operations illustrate language fundamentals. The code demonstrates variable assignment with `let` and `const`, demonstrates the increment operator, and defines functions using both arrow syntax and traditional `function` declarations. While the page shows no data visualization, it introduces core JavaScript concepts in the context of an SVG container. The concrete code uses no specific visualization libraries, relying instead on the browser’s native SVG and scripting support.
