Classification tree modelling

What i want: 1. a web page which works as a canvas 2. a toolbox with 3 items and the user is able to drag items (nodes) to the canvas 3. user can change the properties of each node by double clicking on it 4. each node has a connector. user is able to connect the nodes together based on some rules to make a classification tree 5. auto layout for the classification tree should be provided. The project is a web application which is implemented with .Net technology and MVC. For implementing the nodes and connections i have used [login to view URL] library. I implemented 3 first items that listed above but have no time for the rest (item 4,5). The time is limit!
