F(x,y) = (u, v) · quiver plot · drag to trace a flow line

Controls

u = fx(x, y)v = fy(x, y)

Governing equation

F (x, y) = (P, Q) = (- y, x)

Reading this result: A pure rotation field: every arrow is perpendicular to the radius, so the flow circles the origin with zero divergence and constant curl.
