Voting Tool For Tech Startup Demo

This is a sketch for a voting tool that VCs could potentially use to rate entrepreneurs and companies while they are giving demos. Here is a view that shows the density of votes relative to timestamp. So talk / demo starts, first vote = 0:00, then let's say CEO says they've corned the market or company has some transformational technology at 2:00, everyone votes immediately after that sentence is delivered. That density across all users voting is recorded in this view.
