The Visualization Toolkit provides a number of source and writer objects to read and write popular data file formats. The
Visualization Toolkit also provides some of its own file formats. The main reason for creating yet another data file format
is to offer a consistent data representation scheme for a variety of dataset types, and to provide a simple method to communicate
data between software. Whenever possible, we recommend that you use formats that are more widely used. But
if this is not possible, the Visualization Toolkit formats described here can be used instead. Note that these formats may not
be supported by many other tools.
