Coalescent With Changing Population Size

Explore how time-varying population size changes the geometry of coalescent histories. This interactive view complements the mathematical tutorials with a manipulable demographic picture.

How To Use It

Switch between parametric and piecewise populations, personalize the trajectory, and inspect how changing demographic assumptions reshape waiting times and branching structure.
