Description

After run "High degree node deletion" and use Radial Graph to visualize it. All nodes stay in the left up corner. Can we improve the default layout and try to move all node to the middle of the window?

Other algorithms may have the similar problem

If we move nodes that are in the upper left corner to the middle of the window, they will be mixed in with the part of the visualization that has structure. If we move them, we should only move them when all nodes (except maybe a singleton) are in the upper left hand corner, which should most of the time only be the case with a visualization where there are no edges.

I'm not sure it makes sense to tackle this before Vislayers.

Unless the prefuse visualizations become much higher priority, this is going as won't fix.

Not only does it move singletons to the upper-left hand corner, it moves clusters that have structure there as well. In fact, it seems to only lay out a single arbitrary cluster, and move all other nodes to the upper-left hand corner. This means that the layout is essentially broken for any graph with more than one cluster.'

I added a warning of sorts when you run the algorithm, describing the limitations of the layout. Getting it to work on multiple components would probably not be worth the effort.
