Description

When a plot includes several arrows with different angles, due to them being rotated around their extremity rather than their center (of mass for example), they can easily overlap in the legend. See example attached.
It would make more sense to me for all markers, including arrows, to be rotated around their center of mass in the legend rather than around their extremity.

Research direction

Start by reproducing the attached legend example in plotly.py and identify the legend rendering entry point responsible for arrow marker rotation. Compare the current extremity-based placement with center-based placement, then verify that arrows at different angles no longer overlap in the legend.
