This example demonstrates basic SVG shape rendering, focusing on how simple primitives and paths can compose visual elements. The visualization features overlapping red and green circles, a navy diagonal line, a curved path, and a black polyline on a 960 by 500 canvas. Using raw SVG markup within an HTML document, the code explicitly defines coordinates and styling properties like fill, stroke, and stroke-width for each element. The included YouTube video embedded in the README provides additional context, though the interactive chart itself relies solely on static SVG shapes without data or user interaction.
