- sage.graphs.graph_editor.graph_editor(graph=None, graph_name=None, replace_input=True, **layout_options)¶
Opens a graph editor in the Sage notebook.
Graphinstance (default: graphs.CompleteGraph(2)); the graph to edit
graph_name- a string (default: None); the variable name to use for the updated instance; by default, this function attempts to determine the name automatically
replace_input- a boolean (default: True); whether to replace the text in the input cell with the updated graph data when “Save” is clicked; if this is False, the data is still evaluated as if it had been entered in the cell
