Visustin generates flow charts from Python source code. The support covers both Python 2 and 3. Syntax support is current up to Python 3.5.2.
Other statements are handled as regular statements.
Visustin supports the syntax # -*- coding: <encoding-name> -*-
syntax to detect character encoding when loading a Python source file. Copy & Paste doesn't support it.
Function calls are not followed. They display as a normal statement, not as a jump to the called function.
