Sharing Graph Documents: If you want to share the constructed graph, you can use knowledge graph->export graph document to export a graph document (.xml) that includes the graph's connection information and style settings.

Saving and Opening Graph Documents: When closing the graph window, you can choose "Save" to save the graph constructed on the desktop to workspace->graph node. The saved graph can be opened by double-clicking. Alternatively, right-click on the "Graph" node to import an external .xml document.
