Hi Niranda, There's some examples in tests: https://github.com/apache/arrow/blob/master/cpp/src/arrow/sparse_tensor_test.cc#L187 , https://github.com/apache/arrow/blob/master/python/pyarrow/tests/test_sparse_tensor.py
If you have more questions just ask. Questions are good input for documentation too.
