Hi all,
My name is Fong, I am currently learning to use yfiles with Jupyter notebooks but so far I have encountered issues.
I am currently using this link: https://www.youtube.com/watch?v=M_PbbMVg4ME as a guide but my GraphWidget is not displaying at all, I have attached a snapshot as shown below.
If anyone knows how to overcome this issue, do let me know in the comments. Below is the link to the yfiles github page
Hi,
is the widget loading with an empty graph, or is the widget itself missing?
You could also check whether your queried graph actually contains nodes and relationships, e.g.
print(graph.nodes.__len__())
print(graph.relationships.__len__())
Other than that, you can try the import_from_neo4j.ipynb notebook in the samples of the yfiles-jupyter-graphs GitHub repository.
This should work out of the box, and with the latest release of yfiles-jupyter-graphs (v1.4.2) you can also easily run it in Visual Studio Code if you dislike JupyterLab.
Hi there @fskpf ,
The graph is not empty and has nodes and relationships
However I noticed something different, the graph widget itself is showing when using this code
When I try to use the widget to visualize my graph, the error is shown below

AttributeError Traceback (most recent call last)

----> 5 graph_db=GraphWidget(graph = result.graph())
6 graph_db.show()AttributeError: 'Graph' object has no attribute 'graph'
I can reproduce the same issue when I'm calling graph() twice, e.g.
result = session.run("MATCH (s)-[r]->(t) RETURN s,r,t LIMIT 20").graph()
w = GraphWidget(graph = result.graph())
So try to call graph() only once on the result.
