"Modify line graphs not to display values on points (they get crowded for graphs with a lot of points causing them to be unreadable)" - that sounds like an edge case. I think most people would expect line graphs to have points. Couldn't you calculate if there are more than a certain number, disable them?

Also I don't think this needs to be v11 tagged.

I'm not saying the points themselves would be disabled, but the numbers on them would (because the numbers make the points much bigger than they need to be, causing cramping in some cases... most line graphs in various software do not stick numbers on the points; you use tooltips)

Ah ok I see, makes sense.
