How to read a knitting graph

[ababelle]

So Im making these "cotton" dish clothes for my mother in law.

I have a pattern to spell out our last name B E L L E , I know that is enough, 5 cloths total.

But I want to make one more with a Dressage horse on it for her.

I have a graph pattern, just dotted up to form a shape of a horse and rider. BUT I HAVE NO CLUE WHAT TO DO WITH IT.

How do I read this thing?
