Great PR 👍 Maybe we should consider adding some documentation about the examples in the data folder. What do you think about a new wiki entry or a README file in the /data folder?

Great work 👍 Keep going!

I added a wiki page for data, but I'm not realy happy with it. Do you have ideas?

I like it 🙃 Maybe you could add some sentences about the existing examples too?

I don't feel like that would make a lot of sense, because they are subject to change. This will be a good idea once we have a good network with routes.

Sound reasonable 👍
