+第一章 快速入门
+==============================================================================
+
+画一个简单的有向图
+------------------------------------------------------------------------------
+
+Graphviz 编译的源文件是 dot 文件，把如下的代码保存到 graph01.dot 文件。
+
+.. code-block:: none
+    :linenos:
+    :caption: graph01.dot
+    :name: Graph 01
+
+    digraph G {
+        main -> parse -> execute;
+        main -> init;
+        main -> cleanup;
+        execute -> make_string;
+        execute -> printf;
+        execute -> compare;
+    }
+
+
+使用命令 `dot -Tjpg graph01.dot -o graph01.jpg` 编译，可以得到名为 graph01.jpg
+的图片，图片内容如下所示。

+
+
+让有向图更复杂点
+------------------------------------------------------------------------------
+
+Graphviz 可以给点(node)或者线(edge)添加格式。
