i have created graph using networkx. drawing graph using graphviz, these lines of code: pos = nx.graphviz_layout(g2, prog='neato', args='-goverlap=prism') plt.figure(figsize=(10, 14)) nx.draw(g2, pos, node_size=sizes, alpha=1, nodelist=nodes, node_color=colors, with_labels=true, labels=labeldict, font_size=8) the graph consists of "backbone" of few larger nodes, attached few hundred smaller nodes. i have used args='-goverlap=prism' (in first line of code above) space out graph, has created problem. matters more larger nodes spaced out, but, because of how many small nodes there are, of larger nodes ending crammed together. my thoughts on solution generate graph larger nodes ensure spaced, add smaller nodes graph without changing layout of original nodes. have done research, , seems tricky add new nodes without changing old ones in graphviz. possible "pin" nodes, unsure of how within networkx. this graph looks like: ...
