the graph; the various buttons will allow you to stop and start it.
Note the curved trajectory -- in this case, though the point jumps extremely quickly down below an isocline (remember, when we are above K, the logistic shows exponential decay). The it crawls at a decreasing rate toward the Y-axis, and the end result is extinction of N1.
