Fair point, well made as ever MJD. I would add that as an alternative, you can copy a map as part of your testimony and have it distributed. Then during your oral you can say something like "You should all have a copy of a map I am going to refer to (big pause so they go look for it) and if you'll look at it, you'll see...."
Those maps were part of my written testimony for SB100, HB432 and HB767, so all committee members have a take home copy.
