I actually made Gephi group the airport together based on what connections they have. That mostly ended up grouping them into continents... apart from Heathrow and Charles de Gaulle, which are grouped in together with the Americans. Oops.

Here you go for centrality and here you go for modularity! I had to rerun the algorithm because my Gephi project didn't save correctly for some reason, that's why the layout is different. Thank you for the ideas!

Edit: Just realised that Gephi coloured Heathrow and Charles de Gaulle in with America... I wonder what the British and the French would think about that.

It's in the middle of the American cluster, above Toronto. The reason why it's not that prominent is that the visualisation is based on numbers of connecting flights, and ATL is apparently not ranked that highly there (see also https://simpleflying.com/most-well-connected-airports-in-the-world/)

Thank you!

It's sadly not very up to date, the flight data is up to 2014 and the airport data up to 2019

Hello everyone! I recently created this visualisation for a uni project and thought this subreddit might find it interesting. It represents connections between the world’s 200 largest airports. The circles are airports, with their colour based on the total number of seats in flights connected to them (also to airports not represented in the visualisation) and their size based on how the number of connections with them. The lines are connections between airports, with their weight based on the number of individual routes connecting two airports. The data comes from the World Bank and openflights.org and is sadly not very up to date: Flight data is up to 2014 and airport data up to 2019. The visualisation was created using Gephi and the Force Atlas algorithm.
