How to create a mesh from a csv data file?

I am a spatial design student and have been developing a virtual world in VR with unity. (with no knowledge of coding I might add...). So I hit a technical wall when I was trying to visualise data as a spatial element in unity. The data was collected from instagram in form of a csv. I have managed to visualise the data in 2D using gephi, but have no idea how to do this in 3D to be used in unity with the vive. Has anyone tried this before? many thanks kristina
