First of all, the C core of igraph does not support any visualisation;  
the one that you see in R or in Python are built upon the C core using  
R or Python. GraphML is simply an XML-based graph format; it has  
nothing to do with visualisation, but there are several visualisation  
tools (i.e., Cytoscape) that can load GraphML files and plot them  
nicely. Another way to go is to dump to GraphViz format (which is also  
supported by igraph, at least on the exporting side) and use GraphViz  
to plot the graphs.

For dynamic visualisations, I'd suggest you to try Ubigraph (http://ubietylab.net/ubigraph/ 
). It is effectively a dynamic 3D graph visualiser that you can  
control from your programming language of choice (let it be C++,  
Python, Ruby, whatever) by sending XML-RPC calls to a designated port  
number on your local computer. There are plenty of XML-RPC libraries  
out there, so I'd try coding up something in igraph and Ubigraph using  
an XML-RPC library in whatever language is the most convenient for you.
