>>> reader = pv.PVDReader(filename)

Write the gif to a temporary directory. Normally you would write to a local path.

>>> gif_filename = os.path.join(mkdtemp(), 'dual_sphere.gif')

Generate the animation.

>>> plotter = pv.Plotter()
>>> plotter.open_gif(gif_filename)
>>> for time_value in reader.time_values:
...     reader.set_active_time_value(time_value)
...     mesh =
...     _ = plotter.add_mesh(mesh, smooth_shading=True)
...     _ = plotter.add_text(f"Time: {time_value:.0f}", color="black")
...     plotter.write_frame()
