Data::Dumper and other modules do a great job at dumping data structures. Their output, however, often takes more brain power to understand than the data itself. When dumping large amounts of data, the output can be overwhelming and it's difficult to see the relationship between each piece of the dumped data. Data::TreeDumper also dumps data in a tree-like fashion but hopefully in a format more easily understood. Data::TreeDumper also gives one extraordinary control over output and provides for custom filtering of and iteration over data structures.
