Force-directed layouts

[Kaspar Fischer]

Dear all,

First of all thanks a lot for providing such a useful and elegant  
library to the public! I would like to contribute where I can.

I have read on

http://blog.thejit.org/2009/09/30/force-directed-layouts/

about the upcoming 1.2 release featuring force-directed layouts. I am wondering what the state of this feature is currently? Is the code in the source code repository?

I would like to draw small network graphs incrementally, in the sense  
that double-clicking a node loads, if this has not already happened  
before, its children and adds them to the graph, with the layout  
adjusting itself again until it reaches a local minimum.

Thanks for any pointers,
Kaspar

You could use the sum feature in Graph.op of the existing library to
dynamically add nodes:

I don't understand what will happen then with the layout of the graph?
IIUC the libray has — for general graphs — only the radial layout.
So will this sum operation recompute the radial layout?

You can see the effect of sum (and removing a node) dynamically at the
example: http://thejit.org/Jit/Examples/Hypertree/example3.html

I think it recomputes the entire graph because each node gets a new
position value.
