Inf error when plotting nodes with same x, y location

[jamesmulhern]

When using the x,y,z attribute, and error rises if multiple nodes share the same location.

The exact error text is

ArgumentError: matrix contains Infs or NaNs

It appears to be a LinearAlegbra error that is rising inside the nearest_intersection function.

I was able to circumvent the issue by adding a small random value to each x and y location.
