Construct a graph from a collection of vertices and edges with attributes.
Construct a graph from a collection of vertices and edges with attributes. Duplicate vertices are picked arbitrarily and vertices found in the edge collection but not in the input vertices are assigned the default attribute.
- VD
 the vertex attribute type
- ED
 the edge attribute type
- vertices
 the "set" of vertices and their attributes
- edges
 the collection of edges in the graph
- defaultVertexAttr
 the default vertex attribute to use for vertices that are mentioned in edges but not in vertices
- edgeStorageLevel
 the desired storage level at which to cache the edges if necessary
- vertexStorageLevel
 the desired storage level at which to cache the vertices if necessary

Construct a graph from a collection of edges encoded as vertex id pairs.
Construct a graph from a collection of edges encoded as vertex id pairs.
- rawEdges
 a collection of edges in (src, dst) form
- defaultValue
 the vertex attributes with which to create vertices referenced by the edges
- uniqueEdges
 if multiple identical edges are found they are combined and the edge attribute is set to the sum. Otherwise duplicate edges are treated as separate. To enable
uniqueEdges, a PartitionStrategy must be provided.- edgeStorageLevel
 the desired storage level at which to cache the edges if necessary
- vertexStorageLevel
 the desired storage level at which to cache the vertices if necessary
- returns
 a graph with edge attributes containing either the count of duplicate edges or 1 (if
uniqueEdgesisNone) and vertex attributes containing the total degree of each vertex.
