This graph shows the connections of characters who interact with each other. We understand who is and isn’t present when certain characters are around. We’re able to see a clear connection. However, we don’t know what type of connection there is. There is no info on the basis or context of the characters meeting and interacting. While there are connections shown of who is present within each other’s company, we are missing the information on all sorts of data surrounding the meeting.
