The shape targets::tar_visnetwork() draws for each vertex type, as a
hard-coded copy - they belong to targets, not ggtargets, and are
checked against the installed targets version in the package's own
tests. It is the default shapes of tar_ggplot()/ggplot_dag()/
dag_layers(), so a pipeline's nodes are drawn by type: a regular target
(stem) is a circle, a dynamic-branching target (pattern) a square, and
an imported function and object an up and a down triangle. Imports are
only in the graph with tar_ggplot(targets_only = FALSE).
Value
A named character vector of shape names, one per type. The shapes
a node can take are "circle", "square", "diamond", "triangle"
and "triangle_down".
Examples
targets_node_shapes()
#> stem pattern function object
#> "circle" "square" "triangle" "triangle_down"
dag <- as_dag(

nodes = data.frame(
name = c("a", "b", "c"),
type = c("stem", "stem", "pattern")
)
