# Bounding box for netwokx graph using matplotlib

I have tried to make a graph out of x,y co-ordinates from an area and display it using matplotlib but all the nodes sort of got overlapped as there is little difference between the when compared to the co-ordinates so I need a way to define a bounding box and the scale with which it is supposed to draw the graph [1]: http://imgur.com/6Hwc1

    for i in a:
print i
cur_point = tuple([float(x) for x in i.split(' ')])
print cur_point
assert len(cur_point) == 2
if prev_point is not None:
b = cur_point[1] - prev_point[1]
c = cur_point[0] - prev_point[0]
a = math.sqrt(b ** 2 + c ** 2)
