Sorry for out of topic question, but I really don't know where else I can ask it. I did try to search on the internet but did not come up with anything useful. I am specializing on the back-end development but right now I do need a suggestion for the front end. The user interface for the web application that I need to build shall allow user to create a DAG - directed acyclical graph. Nodes of the graph shall be dragged from the palette and dropped on the canvas and then connected with edges. Edges will be loaded with some conditions and actions as well. User interface shall allow editing - adding/deleting/replacing nodes and edges.
If someone has done something similar and can recommend a framework/toolkit for this kind of front-end development, it will be greatly appreciated. Thanks a lot. Gary Greenberg Staff Software Engineer
