As with the Excel Services service application and
the Access Services service application, the Visio Graphics Services
service application is created by default in SharePoint Server 2010
Enterprise via the wizard in most cases. If a new service application is
needed, it can be created from the Manage Service Applications page on
the Central Administration site.
Visio Graphics Services
allows Visio Web drawings published in VDW format to be shared with
other users who may not have Visio 2010 installed on their computers.
VDW formats can be created only by Visio Professional 2010 or Visio
Premium 2010. Standard Visio drawings (VSD files) are not rendered by
Visio Services and require Visio to be viewed.
An example is shown in Figure 1
of a Visio diagram published using Visio Graphics Services. The
standard options of Open in Visio and Refresh are available, as well as
the ability to view different pages, zoom in or out, and show the Shape
Information Pane visible in the lower-right section of Figure 26.21.
The publishing process is accomplished by accessing the Save & Send
tool from the File tab, selecting Save to SharePoint, and then choosing
the Web Drawing format.
The settings for the Visio Graphics Services service application are as follows:
Global Settings—
Include Maximum Web Drawing Size (50MB limit), Minimum Cache Age
(number of minutes, 34560 maximum), Maximum Cache Age (number of
minutes, 34560 maximum), Maximum Recalc Duration (120 seconds maximum),
Unattended Service Account Application ID.
Trusted Data Providers—
A number of data providers are already provided, or new ones can be
added, using the following types: 1 for OLEDB, 2 for SQL, 3 for ODBC, 4
for ODBC with DSN, 5 for SharePoint Lists, and 6 for Visio Custom Data
Providers.
