Instead of having the markers be circles, if the user passes in an orientation mapping use that to create asymmetrical markers. I'm thinking of using a cubic bezier that looks like a teardrop, something like <path d="M250,219 C112,36 389,36 250,219" />. Couple of things to consider:
Is the right way to do this to add several mappings for the different control points?
Would there be issues making new mappings out of existing mappings?
