[graph-tool] How can I extract the positions of the nodes and edges of the dendrogram obtained from minimize_nested_blockmodel_dl?

Hi. I'm trying to create an interactive web plot with the result obtained form minimize_nested_blockmodel_dl. Until now, I'm able to draw the edges and nodes positions in webgl. However, I have a issue. How can I get the node positions and edges from the dendrogram graph? graph-tool result https://ibb.co/hLKrcxs webgl result https://ibb.co/YLnhy83 ```python state = gt.inference.minimize.minimize_nested_blockmodel_dl(g, ... pos, tg, tpos = state.draw(**options) ``` # beizer control points cts = gt.draw.get_hierarchy_control_points(g, tg, tpos) ``` Thanks
