In the RDF model a statement is represented by three elements: two vertices connected by an edge reflecting the subject, predicate and object of a sentence—this is known as an RDF triple. Every vertex and edge is identified by a unique URI, or Unique Resource Identifier. The RDF model pro...

GES imports graph data based on the property graph. A property graph is a directed graph consisting of vertices, edges, labels, and properties.A vertex is also called a n
A graph $G$ is called vertex decomposable if $\\Delta_G$ is a vertex decomposable simplicial complex. We are interested in determining what families of graph have the property that the complement of $G$, denoted by $\\overline{G}$, is vertex decomposable. We obtain the result that the ...

https://math.stackexchange.com/a/50552/12384 Is the null graph a pointless concept?by Harary and Read The usual argument for considering the null graph not to be connected is that some of the properties that connected graphs with at least one vertex have break down for the null graph. One...

Graph databases use traversal algorithms to query the graph data model. Traversal algorithms may be depth-first or breadth-first, which helps to discover and retrieve connected data rapidly. Scalability Though it’s possible to scale a relation database horizontally (i.e., using sharding), it si...
Rotate a vertex, stop. Then rotate it again Both the rotation handle and the preview shape are not at the right position Expected behavior We should be able to restore the mxGraph code and make the rotation work correctly in this case as well. Screenshots N/A Environment All, the problem...
