Simulation and Visualization

Use this lane when the concise examples work and you want visible artifacts: Rerun streams, simulator traces, and self-contained HTML graph views. Start with the lightweight artifacts before enabling heavier simulator or GUI dependencies.

HTML graph proofpixi run demo-pipeline-html-viz

Writes a self-contained graph artifact and prints a compact ASCII graph.

Mock robosuitepixi run demo-robosuite-mock

Prints mock environment/policy trace lines without requiring robosuite.

TWIST2 Rerun lanepixi run -e twist2 demo-twist2-rerun

Optional visual lane for watching state evolve in a Rerun viewer.

Recommended Order

01Render the graph

Inspect Flows, ports, clocks, sync policies, and feedback edges before changing the example.

02Run the mock trace

Validate environment-as-Flow and policy-as-Flow behavior without simulator install friction.

03Opt into GUI/sim

Use Rerun or real simulator lanes only after the lightweight artifacts match expectations.

What The Artifacts Show

Live HTML artifact

Interactive Retriever graph, embedded from the generated artifact.

Use this before moving to a heavier simulator or robot backend: inspect nodes, ports, clocks, sync policies, and feedback edges in the same HTML view produced by pixi run demo-pipeline-html-viz.

Artifact	Use it for	Dependency level
HTML graph	Inspect structure, ports, and closed-loop shape.	Lightweight.
Rerun viewer	Watch perception or simulator state evolve over time.	Optional GUI.
Mock robosuite trace	Validate environment/policy wiring without simulator install.	Lightweight.
Real simulator lanes	Validate timing with actual simulator dynamics.	Optional/heavy.
