Display Yaw Angle in XY Plot

[siyuanwu99]

Hi!

First thank you for this incredible tool! I have a feature suggestion that I believe would be useful for visualizing navigation data, and I'd love to hear your thoughts on how it could be implemented by plotjuggler plugins.

I would like to replace circular markers in X-Y plots with directional arrows to represent yaw angle (robot's heading). This would allow users to visualize both position and orientation in a single plot, which is particularly useful for debugging navigation algorithms. E.g. arrows could show vehicle's heading at each point, making it easier to understand for developers.

Could you kindly provide guidance on how to implement such feature as a plugin? I've checked the example plugins however most of them are dataloader or transformation. I’d be happy to contribute to this feature if you can point me in the right direction.
