No problem.
Maybe someone knows a nice graph visualization control.

However, it requires graph data as input, completely different from usual linear data used for all other diargam types, so is not easy. > or some force layout like this: > http://bost.ocks.org/mike/fisheye/ Do you mean points-and-lines graph representation or fisheye distortion?

I meant force layouted graph with fisheye distortion. I need to show strong connected components of a graph.

If first, then yes, you can use one point series and one line series to draw such diargam. If second -- the no, currently only single-axis transformations are supported. However, "Cartesian" distortion depicted lower on this page is possible -- see "axistransf" demo for similar example.
