Ruby flow charts

Visustin generates flow charts from Ruby code. Ruby support is current as of Ruby 1.8.7 and 1.9.3. Earlier versions should also be compatible.

Visustin supports standardized Ruby, which intends to be compatible with several alternative Ruby implementations. Support largely conforms to IPA Ruby final draft of 2010, which was accepted as Ruby standards JIS X 3017 and ISO/IEC 30170:2012.
