Hi,  
I have try to use polylinesource feature which nearly matches my needs. .  
Does paraview support any feature that similar to Poly Line Source with inconsecutive vertices connection?  
I want to create a graph, with vertices and edges where vertex can connect to another inconsecutive vertex to create an edge

There is a way to use the **Delaunay 2D** filter to connect vertices based on their Delaunay properties, but you cannot control which vertices are connected.

I used unstructured data graph to visualize the pose graph with points and edges.  
I followed this link to export .vtu file: [20newsgroup/writeNodesEdges.py at master · grzegorzborkowski/20newsgroup · GitHub](https://github.com/grzegorzborkowski/20newsgroup/blob/master/writeNodesEdges.py),  
and load it to paraview to visualize.
