What kind of service is this "data visualization service"?
Is it a library, destined to be linked to an application?
Is it a web service, accessed via an internet protocol? Which one?

This highly depends on the kind of service and how its API
is described.

If it is a library, you make be able to use one of the many
tools that create a binding from C/C++ header files.
If it is a WSDL described web service, you can use a SOAP/WSDL client
library (e.g. "suds") to directly access the service.
etc...
