Hénon Map — Strange Attractor

The classical 2D map x_{n+1} = 1 − a x_n² + y_n, y_{n+1} = b x_n. For (a,b) ≈ (1.4, 0.3), it produces a strange attractor via stretching and folding.

Top notes — brief attractor description and parameter hints.

Side notes — density vs iterations; transients and color choices.

Side notes — typical ranges: a∈[1.2,1.5], b∈[0.2,0.4].

Bottom notes — stretching/folding, measure concentration.
