This example demonstrates basic SVG shape rendering within an HTML page. It shows overlapping circles in red and green, a diagonal navy line, a curved path, and a polyline path, all defined inline within an `<svg>` element. The code uses standard SVG attributes such as `cx`, `cy`, `r`, `fill`, `stroke`, and `d` for path data. The HTML includes CSS to remove margin and hide overflow, and the SVG canvas is set to 960 by 500 pixels.
