Give I have some function (two dimensional), representing some differential equation. How do I point a corresponding phase portrait?

(in each point in some grid, plot an arrow corresponding to the direction of movement in that point for the differential equation)

> I would like to plot a 3d vector field (e.g. a couple of points with arrows attached), with some basic interactivity (rotatate, zoom, pan). What are my options to do this in julia? Are there some example codes with 3d vector fields? Is it possible with Plots.jl?
