When creating a Graph document Node, some types are missing

[alexismenanieves]

I have this definition:

from langchain_community.graphs.graph_document import (
    GraphDocument, Node, Relationship
)

node_list = [('8,650 Btu', 'Node'), ('SO emissions limit', 'Emission Limit'), ('0.03 lb/MMBtu of dry coal feed', 'Node')]
nodes = [Node(id=el[0], type=el[1], properties={'name':el[0], 'type':el[1]}) for el in node_list]

But it returns:

[Node(id='8,650 Btu', properties={'name': '8,650 Btu', 'type': 'Node'}),
 Node(id='SO emissions limit', type='Emission Limit', properties={'name': 'SO emissions limit', 'type': 'Emission Limit'}),
 Node(id='0.03 lb/MMBtu of dry coal feed', properties={'name': '0.03 lb/MMBtu of dry coal feed', 'type': 'Node'})]

The first and last node have 'type' missing. Is that an expected feature of Node?

@alexismenanieves It seems that the type attribute is being omitted from the printed output when it's set to the default value ('Node'). I believe this is an intentional design choice to reduce verbosity, though I agree it can be confusing, especially when type='Node' is explicitly provided during creation. It might be helpful if the printed output always included the type, or if this behavior was documented to avoid misunderstandings.
