ax = tm.plot_frames_in("world", ax=ax, alpha=0.6)
ax.view_init(30, 20)

ax = make_3d_axis(3, 122)
ax = tm.plot_frames_in("A", ax=ax, alpha=0.6)

We will add several transforms to the manager and plot all frames in
two reference frames ('world' and 'A').

In this example, we will demonstrate how to use the TransformManager.
