A minimal single-line comparison chart places two circles connected by a thick black stroke, presenting a two-point data trend without axes or labels. The SVG scatterplot-like layout shows points at (20,20) and (200,60), suggesting a rise in value from left to right. Rendered directly via inline SVG markup on a static HTML page, the example demonstrates basic geometric primitives (_circle_ and _line_ elements) for slope visualization. No JavaScript libraries or data bindings are used, relying solely on hardcoded coordinates and SVG styling.
