Drawing arrow

Hi all,

Is there a way with mapnik to draw an arrow pointing to a given
coordinate: to highlight the destination on a map for example.
If possible, I would like to choose the size (but that might be part
of the style?) and direction of the arrow (or it could be handled by
the anti-collision feature?).

Does such a thing already exist? If not, what would be a good starting
point to implement it?

Thanks,
Emmanuel

No, there is not.
