# Editing a graph

You can edit the graph in a text editor. When you save the changes, Graphviz automatically updates the graph view (Mac OS X 10.3 or later).

- Click on the Edit toolbar item to open the graph statements in your default text editor. If you haven't yet chosen a text editor, or if you press Option while clicking, you can then choose your default text editor from a dialog.
- Edit the graph and save the changes.
- Graphviz automatically renders the graph view. You can also click on the Reload toolbar item to manually render the graph view.
