How to create Visio diagrams from Square Data

Automate the process of entering data into Visio diagrams and keeping your diagrams up to date with the CData ODBC Driver for Square. The driver surfaces Square data as an ODBC data source that can be accessed by applications with built-in ODBC support like Microsoft Office. This article shows how to create a simple diagram to start brainstorming about Visio projects linked to Square data.

Connect to Square as an ODBC Data Source

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.

Square uses the OAuth authentication standard. To authenticate using OAuth, register an app with Square to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

Additionally, you must specify the LocationId. You can retrieve the Ids for your Locations by querying the Locations table. Alternatively, you can set the LocationId in the search criteria of your query.

Connect Square Data to Diagrams

Follow the steps below to use the Data Selector Wizard to import data into your diagram.

1. Open Visio and click File -> New. Open the Brainstorming template.
2. On the Data tab, click Custom Import and select Other OLEDB or ODBC data source. 👁 Selecting a data source
   
3. Select the ODBC option and select ODBC DSN.
4. Select the DSN for Square, select the table you want to import, and finish the wizard. This article uses Refunds as an example.

Link Square Entities to Shapes

Follow the steps below to create a simple diagram that shows how to create shapes from your data, one of the ways to link Square entities to shapes:

1. Click Brainstorming Shapes and drag a main topic onto the drawing page. Enter Refunds as the text of the main topic.
2. Click Topic.
3. Select a row in the External Data window and drag it onto the drawing page.
4. Right-click the Topic shape and click Data -> Edit Data Graphic.
5. Click New Item.
6. In the Data Field menu, select a column. In the Displayed As menu, select how to display them. 👁 A data graphic for a column.
   
7. Drag a few other Square entities onto the drawing page and add association lines back to the main topic, Refunds. New topics have the same configuration: Numeric columns displayed in data bars stand out in contrast to other Refunds entities. 👁 Brainstorming with external data. (Salesforce is shown.)
   

You can refresh your diagram from the Data tab, synchronizing your shapes with the external Square data.
