How do you animate SVG like this?

Question

I just made my first SVG code.
I'm wondering if we can animate it this way:
umm... like... draw like a pencil. Example, if I had a line from top to bottom drawn, animate it so it starts from top and draw that line down.
In this case I drew a 4.
It starts from right -> left -> top -> bottom.
How do I animate it drawing like that

Answer 1

This article explains how you can animate drawing the line, it relies on a trick involving dashed lines. Pretty cool one!
