Since we had to merge all networks into one for measuring anyway, it was simple to convert it into JSON format and to visualize it. By this, we have synthesized the largest Lombardi network ever. An interesting observation is, that this huge graph is not connected if we consider it as undirected. Adding more digitized networks may lead to a connected graph.
Of course, the visualization is not very helpful at all. At least it turns out that Chrome 62 does a better job on this than Firefox 57.
