Visualize Live BigQuery Data in Tableau

Tableau is a visual analytics platform transforming the way businesses use data to solve problems. When paired with the CData Tableau Connector for Google BigQuery, you can easily get access to live BigQuery data within Tableau. This article shows how to connect to BigQuery in Tableau and build a simple chart.

The CData Tableau Connectors enable high-speed access to live BigQuery data in Tableau. Once you install the connector, you simply authenticate with BigQuery and you can immediately start building responsive, dynamic visualizations and dashboards. By surfacing BigQuery data using native Tableau data types and handling complex filters, aggregations, & other operations automatically, CData Tableau Connectors grant seamless access to BigQuery data.
