It's the first time we see this issue.

Seems to come from the computation of the arc, because the path value started with M0,-77.5A for the invisible arc. But starts with M0.001,-77.5A for others.

I still need to investigate if this rounding issue come from the animation interpolation not finishing on the correct value, or if it's the d3.arc() that has an issue with this extreme edge case

It's not the animation, but D3JS that causes the disappearing arc. For an unknown reason modifying the radius impacts this.

Not sure if the solution is on D3 side, or if it's better to have a custom behavior that either ignore too small values or over represent them with that they stay visible for humans
