What I would like to see is a fractal tree being drawn where the you can input an integer, and the output will be a fractal tree with the entered amount of branch steps.

Rules:

• The fractal should be a line fractal tree:
• the shape of the fractal should also be the same as this picture.
• Each branch should decrease by 25% in width for each time it splits
• The final layer of branches should be an 1px wide line
• Shortest code wins
