@mwestphal: Thanks for your willingness to help. I was able to associate the mesh points with my scalar data. My files were: geometry.txt (x,y,z comma separated floating point numbers), connectivity.txt (x,y, z comma separated integer values, each indexing to a specific point in the geometry file), and scalar data text file (floating point values associated with each point in the geometry). I wrote a c++ script that parsed the data and I saved it in .vtp format. I opened the file in Paraview and everything looked like it is supposed to.
