Visustin - Sample flow charts
This page presents sample flow charts created by Visustin, the flow chart generator software. All diagrams were created programmatically with no human adjustment.
Algorithms flowcharted
Below you can find short algorithms flowcharted. You get to see the same code as a flow chart, UML style activity diagram, Visio diagram and a PDF version. See how much easier it is to understand the code by watching the flow chart rather than by reading the source alone.

Greatest Common Denominator flow charts
This example flowcharts the well-known Greatest Common Denominator (GCD) algorithm in various programming languages.
- GCD in C
- GCD in C#
- GCD in COBOL
- GCD in Fortran
- GCD in JavaScript
- GCD in Pascal
- GCD in Perl
- GCD in Python
- GCD in PureBasic
- GCD in REALbasic
- GCD in Visual Basic and Visio version
- GCD in XSLT
- GCD in x86 Assembler
If you're interested, compare GCD in C to the Binary GCD algorithm earlier on this page. The algorithms perform the same task, but look different. The binary algorithm seems more complex, don't you think? There are more loops in the binary algorithm as it plays with the simple bit shift operators (>>). That's the where the "binary" comes in its name. The "regular" GCD algorithm manages with a single loop using the more powerful modulo operator (%).
Flow charts in Word format
Visustin can export flow charts to MS Word documents. It is best suited for relatively small flow charts because of the limited page size in Word. For larger charts PDF is more suitable, as you can easily zoom a PDF in and out.
