SVG Fundamentals
An SVG canvas of 960 by 600 pixels displays fundamental shapes: two circles, a rectangle, a line, and a path. The example shows positioning and styling with fill and stroke attributes, including a circle with `r=50`, a yellow rectangle with a blue border, and a navy diagonal line. It demonstrates basic SVG rendering, which the browser interprets directly from the HTML markup. The code uses plain SVG elements without external libraries, making it a simple introduction to vector graphics on the web.
