This example introduces basic SVG primitives for data visualization. It draws shapes including circles, a line, a path, and a rectangle, with some elements filled in red or green and strokes in navy or brown. The code uses raw SVG elements such as `<circle>`, `<line>`, `<path>`, and `<rect>` within an HTML page. The visualization is rendered as static SVG, with no interactivity, and appears to demonstrate shape fundamentals rather than represent a specific dataset.
