Graphics terminals were a thing that existed. It wasn?t just PLATO that used them.
Graphics terminals were quite rare in the early 1970s, at least at a cost allowing them to
be installed in the hundreds, and with processing requirements low enough for that. I
remember, around the same time, the Tektronix 4010. But that was far less flexible; it
could only draw, not erase, unlike the PLATO terminals.
