• Nodes in the same group are placed on a straight line down the rank.
• All your edges assist nicely in ranking if given the right dir attribute.

案例分析

如果nodesep是左右间距那么ranksep就是上下间距，如果nodesep是上下，ranksep就是左右

• ranksep=0.5 等级间距
• nodesep=0.5 节点间距
• group 使用点一至，节点线成直线
• node[style=invisible]节点不可见
• edge [dir=none style=invisible] 线不可见
