Javascript library for graph operations

Is there any suggested javascript alternative(s) to pythons pygraph or NetworkX? It should be noted that visualization is not necessary (even prefered not to have this).

The library should be able to parse a format capable of retaining labeling and attributes on nodes and edges (DOT, GraphML?). It should support operations such as:

• Listing nodes and edges.
• Given a node, the edges which point in/out to/from it.
• Given a node or edge, return the attached attributes.
• Given开发者_高级运维 two nodes that are connected, determine the most complete path. When running this operation a predicate function should be provided to determine if a node should be included in the search or not.

To put it in context, the web browser based application will traverse the graph from a pre-determined start node. Each node holds an attribute 'userValue' which is compared against conditions (rules?) held as attributes on the nodes out-edges. For the traversal to continue the edge condition must evaluate to true against 'userValue'. The graph will always contain a predetermined start and end (or goal) node.
