Change the marker in yellowbrick plots?

[Aiyu Liu]

Hello,

I have some trouble changing the marker style in some of the Yellowbrick plots. For instance, I know it is possible to do so for the ScatterVisualiser, but I would like to do the same for ValidationCurve also.

May I ask, is this possible?
