Create data visualizations with Azure Data Catalog data in Power Map.
The CData ODBC Driver for Azure Data Catalog is easy to set up and use with self-service analytics solutions like Power BI: Microsoft Excel provides built-in support for the ODBC standard. This article shows how to load the current Azure Data Catalog data into Excel and start generating location-based insights on Azure Data Catalog data in Power Map.
Create an ODBC Data Source for Azure Data Catalog
If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.
You can optionally set the following to read the different catalog data returned from Azure Data Catalog.
- CatalogName: Set this to the CatalogName associated with your Azure Data Catalog. To get your Catalog name, navigate to your Azure Portal home page > Data Catalog > Catalog Name
Connect Using OAuth Authentication
You must use OAuth to authenticate with Azure Data Catalog. OAuth requires the authenticating user to interact with Azure Data Catalog using the browser. For more information, refer to the OAuth section in the help documentation.
When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Import Azure Data Catalog Data into Excel
You can import data into Power Map either from an Excel spreadsheet or from Power Pivot. For a step-by-step guide to use either method to import Azure Data Catalog data, see the "Using the ODBC Driver" section in the help documentation.
Geocode Azure Data Catalog Data
After importing the Azure Data Catalog data into an Excel spreadsheet or into PowerPivot, you can drag and drop Azure Data Catalog entities in Power Map. To open Power Map, click any cell in the spreadsheet and click Insert -> Map.
In the Choose Geography menu, Power Map detects the columns that have geographic information. In the Geography and Map Level menu in the Layer Pane, you can select the columns you want to work with. Power Map then plots the data. A dot represents a record that has this value. When you have selected the geographic columns you want, click Next.
Select Measures and Categories
You can then simply select columns: Measures and categories are automatically detected. The available chart types are Stacked Column, Clustered Column, Bubble, Heat Map, and Region.
