running PyCallgraph on PyCharm

Question

I am trying to run PyCallgraph module on my application. My application runs on Mac and I am running the application from PyCharm Here is what I have tried

def main(url):
    from pycallgraph import PyCallGraph
    from pycallgraph.output import GephiOutput, GraphvizOutput
    graphviz = GraphvizOutput()
    with PyCallGraph(output=graphviz):
        obj = MyApp("agr1")
        obj.extract('372','100001' , '999')

I am getting the following error ...

    libpath/shortest.c:324: triangulation failed
libpath/shortest.c:192: source point not in any triangle
Error: in routesplines, Pshortestpath failed
Traceback (most recent call last):

Process finished with exit code 1

I even tried installing graphviz on my Mac using brew install graphviz and setting $PATH variable on my PyCharm editor as described here pycallgraph with pycharm does not work

I don't know the exact root cause for this and I am stuck at this for last 2-3 days.
