Direction Field for a strange attractor

Built for educators teaching it to a class. Drop a live demo into a lecture or assign it as a shareable link — no lab installs. Simulate a strange attractor live below — adjust the inputs and watch it respond, right in your browser.

Direction Field / Slope FieldLive

dy/dx = f(x, y) · drag the start point

Controls

dy/dx = f(x, y)

▶ Run in Python

Data Inspector

Equationdy/dx = f(x,y)

Curves1

IntegratorRK2

Governing equation

\frac{d y}{d x} = f (x, y) = y - x

Reading this result: Every tick shows the slope dy/dx = f(x,y) at that point; drag the start point and RK2 rethreads the solution curve live, always staying tangent to the arrows. That start point alone picks which one curve you get — click elsewhere to pin extra curves for comparison.
