Here is an example of simple code producing stochastic fractal tree:

.. code:: python

from contextfree.contextfree import *

@check_limits
def branch():
    line(0,1)
    with translate(0,0.9):
        with scale(0.7 + rnd(0.15)):
            with color(alpha=0.95):
                with rotate(-0.3 + rnd(0.3)):
                    branch()
                with rotate(0.3 + rnd(0.3)):
                    branch()

init(canvas_size=(300,300), background_color="#FFFFFF")
with scale(3):
    branch()
    
display_ipython()

Here is the output:
