Adding deployment diagram

Question

I think that deployment diagram feature is missing in PlantUML.

See example here http://www.uml-diagrams.org/deployment-diagrams.html

Answer 1

I use a component diagram, but where components are grouped into nodes named after the server.

E.g.

node web.company.com {
 [httpd]
 [tomcat]
}
[httpd]-->[tomcat] : proxy connection

Answer 2

It's implemented on newer versions of PlantUML.
