Good evening,

Hi,

To visualize a trajectory file (_xtc) and/or coordinate file (_.gro/\*pdb), you can use a visualization software.  
Here some examples [Visualization Software — GROMACS 2021.1 documentation](https://manual.gromacs.org/current/how-to/visualize.html?highlight=visualization)

Best regards
