This package can draw diagrams of hierarchy trees defined in XML files.
The diagram class is a follow-up of another class released here before. Instead of arrays, now it uses XML to define the diagram.
It also implements more features supporting: borders, text colors, fonts, text alignments, backgrounds, paddings, margins, text over the node connections and the thickness of the connections.
The tree XML files define the structure of nodes of the tree as well the graphical attributes that define details of how the diagram should be rendered.
