uml - Generate UML Component Diagram

Question

I'm trying to find a library that creates UML Component Diagram using a config file (XML, Lua, whatever... )

My objective is reach something like this: UML Component Diagram from Visual Studio

I already found PlantUML, but i can't represent Composite Components on it. Does someone have another project ?

EDIT:

I'm trying to find something like Graphviz, and I could the code below. You can try the code using online Graphviz

graph ER {
  SuperComponent [shape=component]
  node SuperComponent {
    comp1 [shape=component]
        facet1 [shape=circle, height=0.12,width=0.12, label=""]
        facet2 [shape=circle, height=0.12,width=0.12, label=""]
    comp1 -- facet1 [label="My Facet1" fontsize=6];
    comp1 -- facet2 [label="My Facet2" fontsize=6];    
  }
}
