[protege-owl] twopi, radial layout of large hierarchies

Hello,

does anybody know how to visualize a class hierarchy developed with protege
in a radial layout like twopi allows?

twopi is supported by GraphViz
(http://www.graphviz.org/Gallery/twopi/twopi2.html).

twopi draws graphs using a radial layout (see G. Wills, Symposium on
Graph Drawing GD'97, September, 1997). Basically, one node is chosen
as the center and put at the origin. The remaining nodes are placed on
a sequence of concentric circles centered about the origin, each a
fixed radial distance from the previous circle. All nodes distance 1
from the center are placed on the first circle; all nodes distance 1
from a node on the first circle are placed on the second circle; and
so forth.

Or is it possible to build a twopi-Tab within protege?
Maybe the following list of graph generators as Tabs:
dot - filter for drawing directed graphs
neato - filter for drawing undirected graphs
twopi - filter for radial layouts of graphs
circo - filter for circular layout of graphs
fdp - filter for drawing undirected graphs

Thanks for help, Oliver
