This is why you use a game/rendering framework/engine if you want to render a single triangle to play around.

This kind of "hardcore requirements to render a single triangle" is what is needed if you wish to have AAA game titles with realistic graphics at 60fps as it gives developers the freedom to do anything they wish.

More freedom -> better graphics at higher performance but more difficult to draw a single triangle.

Less freedom -> easier for beginners to draw a triangle but that is irrelevant in practice because that is not what those APIs are for.
