Information about the graph should be explained more clearly

[RamonMeffert]

The information about the graph graph relations (i.e. weakly/strongly connected, sun graph) is unclear.

• It is probably not clear that you can hover over these items to see more information
• It might also not be clear why this information is present in the first place

To solve the first issue, it might be a good idea to move this information below the graph and just have the expanded view be the one visible all the time. To solve the second issue, another ? button could be added to that section with some information on what these properties represent and why they might be useful in the context of gossip graphs/protocols.
