I’d like to see something like this too, and if I get a chance to put something together useful using Make I’ll post it. Meanwhile I’m using the built-in MacOS Grapher app which seems to be little known but is very powerful (though frustratingly the save/load round trip seems to be very buggy – beware!). Nice video showing its use for phase portraits:
