</html>Configuration
OligrapherEditor has one top-level method, run, which accepts a configuration object with the following attributes:
root:a DOM element to load the graph editor UI intographRoot:`a DOM element to load the graph intooligrapher:an uninitialized copy of the top-level Oligrapher object
Plus any Oligrapher config options. The Editor instance will automatically initialize Oligarpher in editor mode and set up appropriate onSelect and onUpdate callbacks.
Data Source API
Oligrapher 2 Editor allows a user to import nodes and edges from an external data source if a data source object is provided that implements the following API. See build/LsDataSource.js for an example.
findNodes(string, callback)
Accepts a search string and callback and passes an array of matching nodes that conform to Oligrapher's data schema to the callback.
# LsDataSource.findNodes("Obama", function(data) { console.log(data); });

]getNodeWithEdges(newNodeId, existingNodeIds, callback)
Accepts the ID of a node to be added to a graph, an array of the graph's other node IDS, and a callback. Passes a data object to the callback containing the new node and an array of edges connecting the new node to existing nodes on the graph. The node and edges should conform to Oligrapher's data schema.
