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

Hi Tony,

That's cleared a few things up so thank you!

One additional question:

I have done some ego centred graphs for three groups that I'm looking at for my PhD - and I have had to input the data manually because of restrictions as to how much Node XL can obtain quickly. I have read the book on Node XL by Marc Smith (and others), especially the chapter on Twitter. This chapter states that when downloading Twitter data (if you are just looking at followers/following criteria) you can actually map out the links that the alters have to each other. But when I try to do this it doesn't show it - it only shows the links (in or out) the alters have to the ego. How do I do this?

Many Thanks,

Andy
