Exmergo Viz

Exmergo Viz is a component of Exmergo’s data stack that reads the metrics, dimensions, and join paths defined by Dex and turns them into dashboards. It is designed for data teams and business users to collaborate within a governed layer that remains the single source of truth. Viz supports self-service dashboards that reflect the definitions maintained by the engineering workflow.

The tool operates in two steps: first, data teams use Dex to explore the warehouse, author dbt models and semantic definitions, and surface drift; second, Viz reads these definitions and builds dashboards that business users can interact with. The flow emphasizes staying aligned with the semantic layer rather than reinventing definitions for each dashboard.

Viz focuses on business users who need self-serve dashboards while Dex handles the modeling and semantic definitions. The approach keeps modeling work in the dbt project and ensures drift is surfaced as proposed fixes. Dashboards are powered by the governed definitions already in place.

Viz is part of a suite that includes Dex and the dbt Semantic Layer, connected to Snowflake, Databricks, BigQuery, Redshift, ClickHouse, PostgreSQL, and DuckDB. The intent is to provide a visualization layer that works atop a team-owned semantic layer and can be used to build dashboards from established metrics and joins.

Use cases

• Data teams build a foundation with Dex and Viz for business self-service dashboards
• Business users visualize metrics defined by the data team
