You can visualize the trajectory (dump file) with the program OVITO (www.ovito.org). You will have to define few parameters, thought.  Invoke ovito using:

ovito traj.lammpstrj

On the right panel of ovito, under the section "LAMMPS dump" click on the button "Edit column mapping" and enter the fields as specified in the attached png file. On the same panel, tick "File contains a time series" to display the entire trajectory.

A screenshot of these settings is available:
