GGobi: evolving from XGobi into an extensible framework for interactive data visualization
GGobi is a direct descendent of a data visualization system called XGobi that has been around since the early 1990s. GGobi's new features include multiple plotting windows, a color lookup table manager, and an Extensible Markup Language file format for data. Perhaps the biggest advance is that GGobi can be easily extended, either by being embedded in other software or by the addition of plugins; either way, it can be controlled using an Application Programming Interface. An illustration of its extensibility is that it can be embedded in R. The result is a full marriage between GGobi's direct manipulation graphical environment and R's familiar extensible environment for statistical data analysis.
