I got your demo, thank you.
It's a good idea to call NormalizeBreakPoints method of TGraphLink to remove unnecessary break points from your free hand object.
About your questions:
1.rotate the node.
There is not rotate method for nodes, but you can easily implement it using the code introduced in Rotate method of TGraphLink.
2.translate the line to node
You have to implement your own TGraphNode class to support this feature.
3. transparent the node
Set Brush.Style of the node to bsClear.
