SVG Animations and Paths

Question

May anyone clarify the meaning of this code? I know what the shape is. I saw it in action.

<svg width="500" height="500">
<path d="M 0 0 L200 200 L200 0 Z" style="stroke:#000; fill:none;" />
</svg>

I want to know how in the world am I supposed to figure the specific shape a random code (like shown above) generates. Try to explain in simple, understandable terms please. Thank you in advance.
