该插件基于flowchart.js，因此您可以按以下方式定义图表：
```flow
st=>start: Start|past:>http://www.google.com[blank]
e=>end: End:>http://www.google.com
op1=>operation: My Operation|past
op2=>operation: Stuff|current
sub1=>subroutine: My Subroutine|invalid
cond=>condition: Yes
or No?|approved:>http://www.google.com
c2=>condition: Good idea|rejected
io=>inputoutput: catch something...|request
st->op1(right)->cond
cond(yes, right)->c2
cond(no)->sub1(left)->op1
c2(yes)->io->e
c2(no)->op2->e
```
该插件基于js-sequence-diagrams，因此您可以将图表定义如下：
```sequence
Alice->Bob: Hello Bob, how are you?
Note right of Bob: Bob thinks
Bob-->Alice: I am good thanks!
```
