This function infers the layout from the graph structure and is the default
when calling ggraph(). If an x and y argument is passed along, the
manual layout is chosen. Otherwise if the graph is either a rooted tree or a
rooted forest the layout will be dendrogram if the nodes contains a height
variable or tree if not. If the tree is unrooted the unrooted layout will
be used. If the tree is a DAG the sygiyama layout will be used. Otherwise
the stress layout will be used (or sparse_tree if the graph contains more
than 2000 nodes).
layout_tbl_graph_auto(graph, circular, ...)A tbl_graph object
Logical. Should the layout be transformed to a circular
representation. Defaults to FALSE. Only applicable if the graph is a tree
structure
Arguments passed on to the chosen layout
A data.frame with the columns x, y, circular as
well as any information stored as node variables in the tbl_graph object.
