Visualisation

A short tour of how to see a scenario: the plan (geometry, exits, journeys), an interactive replay of a run, and the two overlaid.

import jupedsim_scenarios as js

scenario = js.load_scenario("../assets/journeys.zip")

Run the simulation

result = js.run_scenario(scenario=scenario)

Interactive playback

result.visualise().show()

Plan vs. reality

Pass trajectories=result to overlay the agent paths on the geometry — one figure showing the plan and what the agents actually did.

scenario.plot(show_journeys=True, trajectories=result)
