\brief Various examples demonstrating ROOT's RNTuple columnar I/O subsystem.

RNTuple is the evolution of TTree, offering better performance and new, more robust interfaces. It additionally comes with a binary format specification, [which can be found here](md_tree_2ntuple_2v7_2doc_2BinaryFormatSpecification.html). The tutorials and examples on this page demonstrate how the RNTuple interface can be used for various use cases.
