The main use for this class is to iterate through node-data pairs. The data can be the entire data-dictionary for each node, or it can be a specific attribute (with default) for each node. Set operations are enabled with NodeDataView, but don't work in cases where the data is not hashable. Use with caution. Typically, set operations on nodes use NodeView, not NodeDataView. That is, they use :None:None:`G.nodes` instead of :None:None:`G.nodes(data='foo')`.
A DataView class for nodes of a NetworkX Graph
The following pages refer to to this document either explicitly or contain code examples using this.
networkx.classes.reportviews.NodeView
networkx.classes.reportviews.NodeView.data
Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
