The illustration example in the readme is very impressive. However, I feel the x, y, z ring is a little bit overwhelming to me.
I am NOT suggesting not to showing the ring. But I suggest can we have another mode that only showing the rotation effect on the axis, i.e. like show original +x, +y, +z axes in bold blue, red, green only.

I think colored axis can be useful. For example, for all 24 single qubit Clifford gates, they just permute the axis. Showing the axis only can be very clean and informative. Related to quantumlib/Cirq#4050 that connecting the clifford gate to phased xz gate. Also related to visualize the decompose_rotation that you wrote there.

See the X gate visualization. The animation is fine, but the sphere looks just the same as it was after it, making it hard to compare against the original state.

A solution to this could be making two halves of the axial bands darker/brighter, e.g. the +z half of the x-band (band that is perpendicular to x-axis) dark green and the -z half bright. However, the choice of split will be arbitrary (i.e. why not make it +/- y, instead of z?) which might be a reason not to solve this issue like this.

A marker could be placed on the band, but its position will again be arbitrary.
