BTW: You may add dot attributes to the config files to get additional layouts

# nodes attributes 
[X-UMBRELLO-Dot-Nodes]
type::<widget-type>=<dot-attributes>
# example 
type::class=shape=box
# for all not defined widgets types
type::default=shape=box  

# edge attributes 
[X-UMBRELLO-Dot-Edges]

# for visual representation (export, temporary dot files for auto layout)
visual::type::anchor=arrowhead=none,style=dashed
visual::type::aggregation=arrowtail=odiamond,dir=back
visual::type::composition=arrowhead=diamonds
visual::type::containment=arrowtail=odottee,dir=back
visual::type::dependency=arrowtail=vee,style=dashed,dir=back
visual::type::uniassociation=arrowtail=vee,dir=back
visual::type::association=arrowhead=none
visual::type::generalization=arrowtail=normal,dir=back
visual::type::realisation=arrowtail=normal,dir=back
visual::type::default=arrowhead=none

# for position ranking
ranking::type::anchor=constraint=false
ranking::type::aggregation=weight=0.001
ranking::type::association=weight=0.001
ranking::type::composition=weight=0.001
ranking::type::containment=weight=0.001
ranking::type::dependency=weight=0.001
ranking::type::generalization=weight=1.0
ranking::type::realisation=weight=0.8
ranking::type::uniassociation=weight=0.001
ranking::type::default=constraint=false
# id handling (swap nodes in edge line)
id::type::aggregation=swap
id::type::containment=swap

// other dot attributes 
[X-UMBRELLO-Dot-Attributes]
// graph statement
graph=splines=polyline,rankdir=TB,outputorder=nodesfirst,ranksep=0.5,nodesep=0.5
// main node attributes
node=
// main edge attributes
edge=

// internal settings
