Nodes can contain words

We here at Daft headquarters tend to put symbols (variable names) in our graph nodes. But you don’t have to if you don’t want to.

import daft

pgm = daft.PGM()
pgm.add_node("cloudy", r"cloudy", 3, 3, aspect=1.8)
pgm.add_node("rain", r"rain", 2, 2, aspect=1.2)
pgm.add_node("sprinkler", r"sprinkler", 4, 2, aspect=2.1)
pgm.add_node("wet", r"grass wet", 3, 1, aspect=2.4, observed=True)
pgm.add_edge("cloudy", "rain", label=r"65\%", xoffset=-0.1, label_params={"rotation": 45})
pgm.add_edge("cloudy", "sprinkler", label=r"35\%", xoffset=0.1, label_params={"rotation": -45})
pgm.add_edge("rain", "wet")
pgm.add_edge("sprinkler", "wet")

pgm.render()
