I actually wanted to do that but thought the cost/benefit wasn't high enough - I'd pretty much need to manually place all the airports information on the map if I wanted to use the library I was using (Cytoscape).
Visualizing the DFS at the last step was good enough :) Maybe in the future!
you don't need to do that - just download https://openflights.org/data.html, and plot airport x/y to airport lat/lon directly. Since you're doing only Europe, you don't need to do the sin/cos math do get an accurate projection
