Melwyn,
I saw a treeplot on an Microsoft newgroup research project, it's all html code that you can read from viewing the source of the page.
Navigate to this page:
http://netscan.research.microsoft.com/ReportCard.asp then go down to the thread tracker section and click the + Treeview link. As you hover over the nodes they change other node colors and display additional info about the node.
>Right not i am not aware of HTML.
>I am thinking to do this with Flowchartx(Mindfusions) or Viso Automation.
>Plz let me know which one will be better. Well the members also have their images.
