"Real-time graphics" is typically used in gaming to differentiate between pre-rendered content and content that is rendered on the fly. It's not related to a 1-1 time scale of the content it's displaying. So, my assumption here is that they mean it's actually being rendered as you are using it and at an acceptable framerate, as opposed to the need for it to be simulated, rendered, and played back as a video.

"error" in observations isn't a mistake, for example.

real-time means different things in games and physical simulations.
