I am quite new to both Fortran language and VTK file format.So I have ASCII data(small part of data attached below) and want to write a vtu file for the data. Can someone provide possible guidance or solutions on how to write a fortran code for writing a vtu file

The data is in the following format :

ID | X | Y | Z | R

21477 | 23.763711578028648 | 1.324896330297889 | 21.452167569999407 | 0.001959468036875

you can use VTK fortran wrapping.
