DearAll,<br>
<br>
I plan to evaluate VTK for graph visualization and I wonder
whether it provides the features listed below.<br>
For some features, I already found information online.<br>

- modifying the edge thickness/width according to some edge
weight (???)<br>

<div>Not currently possible. To stress certain edges I normally
use a color map for edges that changes their opacity based on
the weight.</div>

Using the opacity is also a good idea. However, I just discovered
the vtkGraphToPolyData class which should provide access to the edge
geometry. Maybe, by using, e.g., vtkRibbonFilter, I will be able to
change the edge width? I wonder how this would influence the edge
picking in the view.<br>
