why my nodes composed not link correctly ?

Question

Hi, I've started to use plant uml 1 week ago and I have a problem with the link between 2 nodes composed and it's very embarrassing, I hava search all around the internet but, no answer... 

Here is my code :

@startuml
skinparam dpi 300
scale 1.5

node "I" as i
node "G" as g
node "A" as a
node "C" as c

node "Tab" as tab{
    [S] as s
}

node "Ras" as ras{
    [R] as r
}

ras -l- i : USB
ras .r. tab : \r Wi-Fi

g -d- ras : \r      GPIO
g -r- a
r -d- c : \r TBD
g -d- i

@enduml

and here is the result, why the link didn't start from the left for "I" or from the right for "tab" ?

Answer 1

Due to some GraphViz limitation, you should not used -left- and -right- on complex diagram.

In your case, you should do:

A small addition of 'left to right direction' in some cases like this seems to help:
