# Viewing Policies in API Visualizer

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

When deploying a Mule app, make sure that you are using a version of Mule that supports the Policy
visualization. Learn more about which [runtimes are supported](https://docs.mulesoft.com/visualizer/setup#select-a-deployment-type). The
Policy visualization is not supported for API Manager 1.x.

The Policy visualization enables you to see the relationship between Mule app deployments and the
APIs they are implementing and which policies have been applied to those APIs. Data about which
policies have been applied to your APIs comes from API Manager.

The Policy visualization has two modes: _overview_ and _compliance_. Both modes show your deployed
APIs, but each in a different manner:

- _Overview_ mode shows you the number of policies that are applied to each API in your canvas. The
  number on the API reflects this.

- _Compliance_ mode enables you to explore which APIs are compliant with policies that you select.
  Compliance mode is active when you select policies from the **Policies** card; your canvas then
  changes to show which of your APIs are compliant with the policies you selected. The list of
  policies includes custom policies and is grouped by policy category.

When you select multiple policies, the number on the API node represents how many of the selected
policies the API is complying with. A fraction might indicate that your API is not compliant with
all of the selected policies. If an API in the canvas is compliant with all of the selected
policies, it turns green.

## View Information About One Service in Your Network

When you select a node within the graph, the node and its dependency stack are highlighted and all
unconnected nodes are unavailable.

In the Policy visualization, the top card contains information about the Mule app. If the Mule app
is an implementation of one or more APIs, cards for each of the APIs will appear below. The card
will contain the API, version, and instance names as well as a list of which policies have been
applied. The policies are listed in the order in which they are applied and are identified as either
being applied at the API level or as an automated policy.

## Filter Your View

When you select a node, you can click **Select dependents and dependencies**, which selects all
nodes related to the service you selected. If a single node is selected and does not have any
dependents or dependencies, this option is hidden.

You can hide nodes through what you select in the canvas.

- To hide a single node, select it, and then click **Hide selected service**.

- To hide multiple nodes, multiselect them, and then click **Hide selected services**.

- To hide all of the services other than the selected nodes, you can click **Hide other services**.
  If you want to hide everything that is not related to a given dependency stack, select a node and
  then click **Select dependents and dependencies**, which selects all nodes related to the service
  which you selected. Then, click **Hide other services**.

You can search for a node, or _service_, in the **Search services** text field. Services containing
your search in any part of their name are highlighted, while others fade.

## Export Your Network View

You can export the view of your network showing on your canvas to a PNG file by clicking the
**Export as Image** button next to the zoom controls in the bottom right.

- If you customized your view with filters, the customized network topology is exported.

- If you selected specific policies, these settings are reflected in the export.
