mermaid之subgraph的使用

第一步：我们把组件画好

graph TB
    Record>"IPNS Record"]
    subgraph Routing
      Publisher
      Resolver
      Local[("Local store")]
      subgraph Transports
        PubSub[(PubSub)]
        DHT[(DHT)]
      end
    end

第二步：我们添加组件之间的流程（关系）

graph TB
    Record>"IPNS Record"]
    subgraph Routing
      Publisher
      Resolver
      Local[("Local store")]
      subgraph Transports
        PubSub[(PubSub)]
        DHT[(DHT)]
      end
    end
    Resolver-- resolve -->Record-- "(re)publish" -->Publisher
    Publisher-- PUT -->DHT-. GET .->Resolver
    Publisher-- PUT -->PubSub-. GET .->Resolver
    Publisher-- Cache -->Local-. GET .->Resolver-- Cache -->Local
