geom_dag_point are very similar to
ggplot2::geom_point but with a few defaults changed.

geom_dag_point plots a single point.

Set of aesthetic mappings created by

inherit.aes = TRUE (the default), it is combined with the default mapping

NA, the default, includes if any aesthetics are mapped.

TRUE always includes.
It can also be a named logical vector to finely select the aesthetics to
FALSE, overrides the default aesthetics,
rather than combining with them. This is most useful for helper functions
that define both data and aesthetics and shouldn't inherit behaviour from
the default plot specification, e.g.
geom_dag_point understand the
following aesthetics (required aesthetics are in bold):
geom_dag_node also accepts:
