+=head1 SYNOPSIS
+
+    my $graph = Graph::GEXF->new();
+
+    my $n = $graph->add_node;
+
+=head1 DESCRIPTION
+
+=head2 ATTRIBUTES
+
+=head3 id
+
+    my $n = $graph->add_node(1);
+    $n->id; # returns 1
+
+The B<id> of a node can't be changed once the node is created.
+
+=head3 label
+
+    $n->label('franckcuny');
+    $n->label();
+
+Each node has a label. If the B<label> is not defined, the default value is the B<id>. This value can be changed at any time.
+
+=head2 METHODS
+
+=head3 link_to
+
+   my $n1 = $graph->add_node();
+   my $n2 = $graph->add_node();
+   my $n3 = $graph->add_node();
+
+   $n1->link_to($n2->id);
+   $n1->link_to($n3->id);
+
+   # or
+   $n1->link_to($n2->id, $n3->id);
+
+This method will create an edge between some nodes.
