states = ['idle', 'running', 'stopped']
transitions = [
    {'trigger': 'start', 'source': 'idle', 'dest': 'running'},
    {'trigger': 'stop', 'source': 'running', 'dest': 'stopped'}
]

machine = ReactFlowMachine(
    states=states,
    transitions=transitions,
    initial='idle'
)
graph_data = machine.get_graph()
# Returns: {'nodes': [...], 'edges': [...]}
