SVG Principio
This example demonstrates a basic SVG scene composed of three circles positioned horizontally, with the first circle using the default black fill and the other two explicitly colored blue and green. A thin blue rectangular outline frames the entire drawing area, while an incomplete line element with an empty x1 attribute suggests an unfinished or minimal structure. The code uses raw SVG markup within an HTML document, relying on standard SVG circle, rect, and line elements. The rendering approach is purely declarative, with no JavaScript libraries or data sources involved.
