Careful with this 'to scale' thing. I guess it depends on who publishes the plate, but round here the plan view is to scale. Definitely within the 10nm circle, obstacles etc have been placed on the ground where the plate says they are supposed to be
.
Having said that, as
ea says, the graphic describing the holding pattern/procedure turn is not to scale. It's more of a pictoral aid to the pilot to let him know what side of the inbound track he should be on. And that's the other mandatory item, if it says left hand turns, you do left hand turns. The other side of the inbound track is not guaranteed to be protected airspace.
