This example shows a single black circle on a blank canvas. The SVG element is set to a width of 960 and a height of 500, and the circle is given a radius of 200, which determines its size. The page uses inline SVG directly within an HTML document, with the body styled to remove margins and hide overflowing content. The visualization is static, with no interaction or animation, and the circle is rendered without any specified fill color, appearing black against the white background.
