Component Diagram

http://plantuml.com/component-diagram

You can use several keywords to group components and interfaces together:

• package
• node
• folder
• frame
• cloud
• database

@startuml
package "Some Group" {
  HTTP - [First Component]
  [Another Component]
}
node "Other Groups" {
  FTP - [Second Component]
  [First Component] —> FTP
} 
cloud {
  [Example 1]
}
database "MySql" {
  folder "This is my folder" {
    [Folder 3]
  }
  frame "Foo" {
    [Frame 4]
  }
}
[Another Component] —> [Example 1]
[Example 1] —> [Folder 3]
[Folder 3] —> [Frame 4]

Class Diagram 类图

http://plantuml.com/class-diagram

You can use the interface, annotation and enum keywords too.

@startuml
abstract class AbstractList
abstract AbstractCollection
interface List
interface Collection
List <|— AbstractList
Collection <|— AbstractCollection
Collection <|- List
AbstractCollection <|- AbstractList
AbstractList <|— ArrayList
class ArrayList {
  Object[] elementData
  size()
}
enum TimeUnit {
  DAYS
  HOURS
  MINUTES
}
annotation SuppressWarnings

Graphviz

Graphviz 画一个 Hash Table

digraph g {
    rankdir=LR;
    node [shape=record,width=01,height=.1];
  a[label="<1>Hash Table|<2>Node|<3>Node|...|<4>TreeNode"];
    {
        node1[label="{<1>A1|<2>A2|...|An}"]
        node2[label="{<1>B1|<2>B2|...|Bn}"]
        subgraph cluster_treenode{
            penwidth=0;
            node[shape=circle];
            root[label="", style=filled,fillcolor=black,width=.2];
            n1[label="", style=filled,fillcolor=red,width=.2]
            n2[label="", style=filled,fillcolor=black,width=.2]
            n3[label="", style=filled,fillcolor=black,width=.2]
            n4[label="", style=filled,fillcolor=red,width=.2]
            n5[label="", style=filled,fillcolor=black,width=.2]
            n6[label="", style=filled,fillcolor=black,width=.2]
            root->n1;
            n1->n2;
            n1->n3;
            root->n4;
            n4->n5;
            n4->n6;
        }
    }
 
    a:2:e->node1:1 [style=dashed];
    a:3:e->node2:1;    
    a:4:e->root;    
}

Graphviz 画证书链

digraph G {
 nodesep=1.0 // increases the separation between nodes
 "Class 3 Public Primary Certification Authority" [style=filled, fillcolor=green] 
 "VeriSign Class 3 Public Primary Certification Authority - G5" [style=filled, fillcolor=cyan] 
 "DigiCert Global Root G2" [style=filled, fillcolor=cyan] 
 "DigiCert Global CA G2" [style=filled, fillcolor=peru]
 "Server证书" [style=filled, fillcolor=peru]
 "Class 3 Public Primary Certification Authority"->{"VeriSign Class 3 Public Primary Certification Authority - G5"}
 "VeriSign Class 3 Public Primary Certification Authority - G5"->{"DigiCert Global Root G2"}
 "DigiCert Global Root G2"->{"DigiCert Global CA G2"}
 "DigiCert Global CA G2"->{"Server证书"}
}

Graphviz 画公司部门结构

digraph hierarchy {
  nodesep=1.0 // increases the separation between nodes
  node [shape=box] //All nodes will this shape
  edge [color="#D9D9D9", style=dashed] //All the lines look like this
 
  总经理->{市场部 人事部 技术部}
  市场部->{销售处 广告处}
  技术部->IT经理
  {rank=same;IT经理 销售处 广告处}  // Put them on the same level
}

Graphviz 画模块依赖图

digraph G {
    main -> parse -> execute;
    main -> init;
    main -> cleanup;
    execute -> make_string;
    execute -> printf
    init -> make_string;
    main -> printf;
    execute -> compare;
}
