For treating VTK data on Julia, Mohamed Tarek makes related libraries. I really appreciate his works. After Pkg.clone VTKDataTypes.jl & VTKDataIO.jl, you may have to resolve some dependencies.

For reading VTK, you can use the following:

using VTKDataTypes
using VTKDataIO

data = read_vtk("m000000.vts")

data. point_coords is coordinate data, and data.point_data is a dictionary data.
