Creat relation between blocks by click “link” and drag between two blocks.
Change the text of block by double click it.
Change the if branch block by clicking it and press tab.
Scale up and down by scrolling.
Delete graph.
Import json to generate graph or dump graph into json.
Dump the graph into C-language described Code, support if, while, and do-while structure.

Examples:
