I am trying to get started.
Pajek does well with outputing 2D graphs, e.g as SVG or JPG, but suggests X3D and several other choices for 3D output.
I would prefer a Blender solution for visualization of 3D graphs because of Blender's additional capabilities, if I succeed with getting the hang of it for simple uses, as I am a total novice with Blender now.
Blender does not complain about the X3D file I output from the Trade.net sample data set for Pajek on relations between nations in global trade. But Blender by default does not display the nodes and edges of the national_trade_graph.x3d I exported, just a cube with a central set of blue, red, and green axes around an orange square surrounded by orange and white circles.
If you have a suggestion to point out how to have Blender display the nodes (nations) and edges (trade) I would appreciate it.
Additionally, I only found one reference to use of Blender (for astronomical data), but none for social network data; if you know of any others using Blender like I want to, I would appreciate it.
I can provide sample data, a JPG image and the X3D file if you want.
I am willing to read the fine manual for Blender if you can point out to me where. Otherwise I will go back to Youtube tutorials.
Original data, JPG 2D image, and X3D file, requested by Duarte Farrajota Ramos in his edit, are hopefully now in Blend-Exchange but original data file, Trade.net provoked the message "You can't upload files of this type.", and national trade graph.jpg provoked same message, and also for national_trade_graph.x3d so my Upload there seems to be a failure. I guess Blend-Exchange is limited to .blend files.
I next tried Google Drive where I succeeded in uploading the files (and included national_trade_graph.x3d.blend) and have a link readable by anyone with it, no sign-in required https://drive.google.com/drive/folders/13xNc92zIJ2iAUwIekMRzbhgOjANKkfdr?usp=sharing
I saved national_trade_graph.x3d.blend and attempted to upload it to Blend-Exchange but got the message for this URL, https://blender.stackexchange.com/posts/143893/edit "The provided url is not valid, please copy and paste the entire url, including the "https://" header." I tried without the /edit but got same error message.
I hope with that trail of partial failure there may be clues of what I might do to correct the provision of data and graphs for this discussion.
