FAST(Flowchart Abstract Syntax Tree) SDK is a development toolkit built upon Eclipse RCP and GEF to visualize the process of converting unstructured flowcharts in to structured ones.
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
