This is a simple demonstration of a chatbot whose behavior is programmed using a visual editor. In this implementation, all elements are customized, including animated connections. The chat window is presented as a separate node that can be moved only using special handles at the bottom and top. A dataflow and control flow-based engine is used to process the graph. There is also validation of connections by checking socket compatibility.

DataflowEngine and ControlFlowEngine are being used here, just like in the Hybrid engine example.

Validation of connections carried out by extending ClassicPreset.Socket and including a corresponding method that takes in another socket as an argument and checks for compatibility. If the sockets are incompatible, a message is displayed and the connection is not added.
