How to create Visio diagrams from Google Calendar Data

Automate the process of entering data into Visio diagrams and keeping your diagrams up to date with the CData ODBC Driver for Google Calendar. The driver surfaces Google Calendar 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 Google Calendar data.

Connect to Google Calendar 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.

You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.

Connect Google Calendar 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 Link Data to Shapes.
3. Select the ODBC option and select ODBC DSN.
4. Select the DSN for Google Calendar, select the table you want to import, and finish the wizard. This article uses VacationCalendar as an example.

Link Google Calendar 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 Google Calendar entities to shapes:

1. Click Brainstorming Shapes and drag a main topic onto the drawing page. Enter VacationCalendar 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.
7. Drag a few other Google Calendar entities onto the drawing page and add association lines back to the main topic, VacationCalendar. New topics have the same configuration: Numeric columns displayed in data bars stand out in contrast to other VacationCalendar entities.

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