Calligra Flow (formerly Kivio) is free diagramming software that is a part of Calligra Suite, an integrated graphic art and office suite by KDE.
Flow is a flowcharting and diagramming application for the Calligra Suite and has a user interface that is similar to Microsoft Visio. It is fully integrated into Calligra and can for example be embedded into Calligra Words.
Kivio was originally developed by theKompany who brought the source code of a Linux-only version into KOffice under GPL. A proprietary version also compatible with Mac OS X 10.3 and Windows 9x–XP was also released under the name Kivio mp. The last release of Kivio mp was version 3.0, made in December 2004. That release was based on Qt 3.
The GPL versions followed the version scheme of KOffice. The last stable version was 1.6.3, released on June 8, 2007. Since then Kivio continued to be developed without maintainer and no stable releases seeing the light of day.
After the split of the KOffice developer community in 2010, the Kivio code was imported into the newly formed Calligra project and picked up by a new maintainer who renamed the application to Calligra Flow. A stable release was made along with the rest of Calligra Suite 2.4.
