+Chapter 1: Graph
+======================
+
+:ref:`(中文版)<guide_cn-graph>`
+
+Graphs express entities (nodes) along with their relations (edges), and both nodes and
+edges can be typed (e.g., ``"user"`` and ``"item"`` are two different types of nodes). DGL provides a
+graph-centric programming abstraction with its core data structure -- :class:`~dgl.DGLGraph`. :class:`~dgl.DGLGraph`
+provides its interface to handle a graph's structure, its node/edge features, and the resulting
+computations that can be performed using these components.
+
+Roadmap
+-------
+
+The chapter starts with a brief introduction to graph definitions in 1.1 and then introduces some core
+concepts of :class:`~dgl.DGLGraph`:
+
+* :ref:`guide-graph-basic`
+* :ref:`guide-graph-graphs-nodes-edges`
+* :ref:`guide-graph-feature`
+* :ref:`guide-graph-external`
+* :ref:`guide-graph-heterogeneous`
+* :ref:`guide-graph-gpu`
