Browser based drawing area

Looking for someone to develop a browser based drawing area to be used as a user interface to previously developed data access logic. The user should be able to select an icon, drag the icon into the drawing area then link that icon to 1 or more icons in the drawing area. This is a logic diagram but unlike a visio diagram, the icon can link elements to multiply objects in the drawing area. If you envision a data base table with 10 columns, column 1 would link to column 1 in another table and column 2 to a column in a 2nd ? or 3rd table. After the user finishes the ‘drawing’ I need the ability to export that document to ? xml and recall it for further editing. Since the icon is a representation of a background process, I need the ability to edit the attributes of the icon to call the appropriate logic to include database connect information (the logic has been developed, I just need the user interface), processing rules, etc. ? ## Deliverables * * *This broadcast message was sent to all bidders on Monday Mar 10, 2008 8:09:32 AM: I'd like to make a decision on this project by Friday 3/14/2008,if you haven't done so already, please let me know the technology you are proposing.
