ctioga2 version 0.4 is out and brings in a whole bunch of new features, such as a fully-fledge styling system and a few other more. This version of ctioga2 is much more flexible: the styling system now makes it easy to change the whole look of a plot with just a few localized changes !

You can get the new version there:

Enjoy !
