SVG Fundamentals
This example demonstrates fundamental SVG shapes and attributes for data visualization, using a static canvas with rectangles, circles, lines, and a custom path. The SVG element is 800 by 600 pixels, and the code shows how to set coordinates, dimensions, colors, and stroke properties directly in markup. It includes a blue outlined rectangle, red and default-black circles, navy and blue lines for alignment guides, and a purple rectangular path drawn with the `d` attribute. The example uses no external libraries, relying purely on inline SVG and standard HTML, with a straightforward rendering approach suitable for learning basic vector graphics primitives.
