-The Data Graph is a semantic layer that unifies all your customer datasets, letting you define and manage relationships between any entity data set in your warehouse (accounts, subscriptions, households, products) and the Segment Profiles you send with [Profiles Sync](/docs/unify/profiles-sync/). 
+The Data Graph acts as a semantic layer that allows businesses to define relationships between various entity datasets in the warehouse — such as accounts, subscriptions, households, and products — with the Segment Profile. It makes these relational datasets easily accessible to business teams for targeted and personalized customer engagements.
 
-By linking these datasets, the Data Graph turns complex relational data into actionable insights, enabling marketers and business stakeholders to create targeted, personalized customer interactions.

This tool accelerates audience creation, enabling precise targeting, enhanced customer personalization, and optimized marketing spend without the need for constant data team support.
 - **[Linked Events](/docs/unify/data-graph/linked-events/)**: Allows data teams to enrich event streams in real time using datasets from data warehouses or lakes, and send these enriched events to any destination. Linked Events is available for both Destination Actions and Functions.

-**Option 1 (Most common):** Use the `external_id` block to join the profile entity with an entity table using external IDs from your [Unify ID resolution](/docs/unify/identity-resolution/externalids/) settings. Typically these identifiers are  `user_id`, `email`, or `phone` depending on the column in the entity table that you want to join with.

 - `type`: Represents the [external ID type](/docs/unify/identity-resolution/externalids/#default-externalids) (`email`, `phone`, `user_id`) in your id-res settings. Depending on if you are using materialized or unmaterialized profiles, these correspond to different columns in your Profiles Sync warehouse tables:
