Pitchfork bifurcation
Description
Left pane represents the parameter space (equilibrium states vs. parameter). The position of the stable equilibria is marked with red curves (continuous for stable equilibria, and dashed for unstable ones). Red dots represent equilibrium states (filled for stable, empty for unstable). The light blue point can be clicked and dragged to modify the value of the parameter. Around this point, we represent the flow in the line.
Right pane represents the time space (state vs. time). In blue, we plot several time series (differing in initial conditions).
