Aqueduct is a simple state machine library written in Java. Some programs can be described naturally as a state machine or a flowchart; this library is intended to simplify the development of such programs.
JLink lets users author flow charts based on ISO 5807 and IBM standards. Developers can use JLink to add flowcharts to applications, serve a flow chart over the web in PDF or PNG, or dynamically create a flowchart with Javascript, Python or Ruby scripts
