Simulation cell:
Currently you iterate multiple times over all agents, is there a better way to do it?

For example:

while simulation.agent_count() > 0:
    # Find leader's position
    if leader_id in simulation.removed_agents():
        leader_id = None
    if leader_id:
        position_leader = simulation.agent(leader_id).position

    # Move followers towards leader
    for agent in simulation.agents():
        if agent.id == leader_id:
            continue

        # Define a target position near the leader with some randomness
        near_leader = (
            position_leader[0] + random.normalvariate(1, 0.1),
            position_leader[1] + random.normalvariate(1, 0.1),
        )
        near_leader_point = Point(near_leader[0], near_leader[1])

        # If the target position is inside the walkable area, set it as the agent's target
        target = (
            near_leader
            if any(geom.contains(near_leader_point) for geom in area.geoms)
            else position_leader
        )
        agent.target = target

        # Check if the agent reached the exit and mark it for removal if so
        if Point(agent.position).distance(exit_area.centroid) < 1:
            simulation.mark_agent_for_removal(agent.id)

    simulation.iterate()

Nice!
