+### Object structure
+
+```js
+import {Graph,Color} from '@sapphirecode/graphviz-builder';
+
+// create a new graph
+const g = new Graph('foo');
+
+// add a node to the graph
+// this function returns the full name of the node that's later used for creating edges
+const bar = g.add_node('bar');
+
+// if you want to specify attributes
+const baz = g.add_node(n => {
+  n.name = 'baz';
+  n.label = 'node baz';
+  n.color = Color.red;
+});
+
+// connect nodes
+g.add_edge(bar, baz);
+
+// add a subgraph
+g.add_graph(sg=>{
+  sg.name = 'subgraph';
+
+  sg.add_node('foo');
+})
+```
