Commented Unassigned: The position of vertices in a graph [25611]

Hi - First time 'poster!' - I am just having a play about with NodeXL at the minute and am wondering about the position of nodes within the graph (currently set on Fruchterman-Reingold). I am splitting the graphs from certain Twitter accounts into three different formats: one for 'followers/following,' one for 'mentions,' and one for 'replies.' The graphs are circular, why do some nodes appear closer to the main user in the centre than others? I gather that for 'followers/following' a mutual follower/following relationship corresponds to why people appear closer to the main user in the centre, but how are their positions determined?

Cheers,

Andy

Hello, Andy:

It's definitely a shame.

I'm not sure what you mean by "input it manually." Where would you get the follow data to manually input? The problem is obtaining the data, which Twitter has made very difficult for us.
