+AutoGL uses ``AutoGL Dataset`` to maintain datasets for graph-based machine learning, which is based on the dataset in PyTorch Geometric or Deep Graph Library with some support added to corporate with the auto solver framework.
 
 Different graph-based machine learning tasks are solved by different ``AutoGL Solvers`` , which make use of four main modules to automatically solve given tasks, namely ``Auto Feature Engineer``, ``Auto Model``, ``Neural Architecture Search``, ``HyperParameter Optimization``, and ``Auto Ensemble``.
