I'm working on a graph with (x,y) node coordinates randomly picked from 0-100. If I simply plot the graph using nx.draw() and passing the original coordinates it looks ok, but if I try to plot some node sizes in a way it relates to coordinates it looks clearly inconsistent.
Looks like the nodes position parameter in draw() is not in the same unit of the node sizes, which are in pixels.Sadly there's nothing about position units in NetworkX documentation...
Networkx uses matplotlib to plot things. It does not use pixels for its coordinates, and for good reason.
If you you have coordinates whose values range from -0.01 to 0.01, it will produce a plot that scales the upper and lower bounds on the coordinates to be large enough to hold this, but not so large that everything is in a tiny little bit of the plot. If you now add points with coordinate values around 100, it will rescale the plot to show these as well.
Think about how it would look to plot the line y = x+1 for x in (-0.5, 0.5) if matplotlib insisted that 1 had to correspond to a pixel.
