How to work with pseudo-graphics in the terminal?

Question

Programming

I was always interested in the question, and only recently I thought of asking - how, in what mode or due to what in the terminal can I use pseudo-graphics in the terminal? I don't know how to express myself exactly. As examples - games like ADOM or Dwarf Forteress? Or some programs with a pseudo-graphical interface. They are not interested in libraries on which this can be done, but in the principle itself, which way to look, which word to google.

We clear the screen or part of it and display new characters - what else is there to explain?
