Nodes can go free

You don’t need to put ellipses or circles around your node contents, if you don’t want to.

from matplotlib import rc
rc("font", family="serif", size=12)
rc("text", usetex=True)

import daft

pgm = daft.PGM([3.6, 2.4], origin = [1.15, 0.8], node_ec="none")
pgm.add_node(daft.Node("cloudy", r"cloudy", 3, 3))
pgm.add_node(daft.Node("rain", r"rain", 2, 2))
pgm.add_node(daft.Node("sprinkler", r"sprinkler", 4, 2))
pgm.add_node(daft.Node("wet", r"grass wet", 3, 1))
pgm.add_edge("cloudy", "rain")
pgm.add_edge("cloudy", "sprinkler")
pgm.add_edge("rain", "wet")
pgm.add_edge("sprinkler", "wet")
pgm.render()
pgm.figure.savefig("nocircles.pdf")
pgm.figure.savefig("nocircles.png", dpi=150)
