!SUBSECTION First Steps with Graphs

A Graph consists of vertices and edges. The vertex collection contains the
documents forming the vertices. The [edge collection](../Glossary/README.html#edge_collection) contains the documents
forming the edges. Together both collections form a graph. Assume that the
vertex collection is called *vertices* and the edges collection *edges*, then
you can build a graph using the *Graph* constructor.

```js
arango> var Graph = require("org/arangodb/graph").Graph;

arango> g1 = new Graph("graph", "vertices", "edges");
Graph("vertices", "edges")
```
It is possible to use different edges with the same vertices. For instance, to
build a new graph with a different edge collection use

```js
arango> var Graph = require("org/arangodb/graph").Graph;

arango> g2 = new Graph("graph", "vertices", "alternativeEdges");
Graph("vertices", "alternativeEdges")
```

It is, however, impossible to use different vertices with the same edges. Edges
are tied to the vertices.
