Research direction

Start by reviewing the graph export path for GML and the Dash integration, then consult the linked Plotly Community Forum discussion about returning node positions. Investigate whether positions can be retrieved from Cytoscape.js after layout or dragging. Done means exported GML includes the dynamically generated node positions and the behavior is covered by an appropriate test.

Written by the indexing model from the issue text.

Description

enhancement

At the moment, there is no way to retrieve node positions dynamically generated by the layout (e.g. force layout, cose, etc) in Dash or by user dragging.

They are not stored in the Python graph object. They possibly can be retrieved from the JS using Cytoscape.js, however, this solution is not trivial.

Created a Plotly Community Forum post: https://community.plotly.com/t/dash-cytoscape-returning-node-positions-from-layout/23818/2
