For a long time it was still a useful teaching language. On how many languages can you simply make two statements and have a line drawn on the screen?

SCREEN 9

LINE (100,100)-(200,200)

I only know processing that has this kind of ease of use. But any curious kid, given a BASIC interpreter and the LINE instruction will start drawing stuff around, naturally come to loops, and so on, without having to worry about the details of "real" programming languages.
