Hi David,
Thanks for last and this replies. You have an other cool demo.
I read the code, please correct me if I am wrong, it seems you use
Nodes=new Array()
in Javascript code for the link between the node and the line.
In other word, if the user creates the graph, this information along
with the svg object have to be stored to the server for the user to
reload his design the next day.
I am thinking to use <g .. /> and the hidden text to store the
information. The circle (rect in your demo) should know which line
and which end of the line it is attached. Do you know anybody has
simular experance that can be shared?
Thanks,
Tak
