This example demonstrates the foundational structure of an SVG graphic, displaying a single circle positioned within an SVG canvas. The code uses a minimal HTML page with inline SVG markup, defining the circle's center coordinates and radius directly through the `cx`, `cy`, and `r` attributes. This illustrates how SVG primitives form the basis for data visualization, with the circle rendered as a static shape without any data binding or interactivity. The example is built with plain HTML and JavaScript, relying solely on the browser's native SVG support rather than a charting library.
