This example is an SVG practice sheet showing a scatter plot inside a large bordered frame. It demonstrates the use of the SVG `circle` element to plot various data points at different coordinates, each with a fixed radius and black fill. The chart is drawn using plain SVG markup within an HTML document, without any JavaScript libraries. A small rounded rectangle in the top-left corner, outlined with a subtle black stroke, functions as a label or annotation box. The overall layout emphasizes SVG coordinate positioning and basic shape rendering for static data visualization.
