Cobweb is a Java applet for real-time network visualisation; its strength lies in the interactive exploration of networks. Therefore, it allows adding new nodes interactively to a network by querying a database on a server.

One major focus while developing the applet was to enable the user to interact with the network directly and smoothly in a pleasant way. To achieve this, nodes can be dragged and dropped interactively; the network is constantly rearranged. Cobweb provides a side-bar that shows further details concerning selected nodes or edges; the side-bar can also contain buttons to interact with the network. The applet is also able to load and display additional data at runtime, so that it is possible to start with one node and explore the network by loading neighbouring nodes into the network. The information about new nodes is obtained by calling a script on the server that can e.g. query a database.

Cobweb is capable of reading and writing XGMML- and GraphML-documents to load and store the networks that are displayed.
