   **discoal demo of selective sweep simulation.** Panel A: Deterministic sweep trajectories for strong and weak selection. Panel B: Diversity reduction profile around a hard sweep -- simulation (green) vs the Maynard Smith & Haigh approximation r/(r+s) (dashed red), showing a clear valley of reduced diversity centred on the selected site. Panel C: TMRCA distribution under a sweep (linked site) vs neutral coalescence -- sweeps dramatically reduce coalescence times. Panel D: Sweep duration vs selection coefficient, matching the theoretical prediction.

This figure was generated by running the ``mini_discoal`` implementation
on data simulated with ``msprime``. The script is at
``figures/fig_demo_discoal.py``.
