# Directed Acyclic Graph (DAG)

##  Overview

* The Directed Acyclic Graph (DAG) is a useful tool for checking and understanding data models. By representing your data model as a DAG, you can easily visualize relationships, dependencies, and the overall structure of your data.

* To open, click on the main page of Data then click on the Graph tab on the left menu sidebar.

* The DAG will display the data model showing relationships between them.
* Click the Editor tab to come back to the main Data page if the left side menu is closed.

## Customize the DAG&#x20;

* You can add any content just like the [AI Text note](/docs/dashboard/widget-types/ai-text-note.md) widget.

* Any actions that change the position of date models will activate the Save button. You should click it if you have done customizing your DAG.
* Click the Discard button to revert it back.
