Arguments

graph

a dgr_graph object, created using the create_graph function.

a string where "forceDirected" is the default whereas "constant" is another layout option.

positions

data.frame of two columns x and y with fixed positions if you intend to provide preset positions for nodes.

width

string or integer with a valid CSS width for the container for our htmlwidget.

elementId

string with a valid CSS id.
