>Generation of diagrams and flowcharts from text in a similar manner as markdown.
|
|
|
|
Ever wanted to simplify documentation and avoid heavy tools like Visio when explaining your code?
|
|
|
|
|
|
This is why mermaid was born, a simple markdown-like script language for generating charts from text via javascript. [Try it using our editor](http://knsv.github.io/mermaid/live_editor).
|
|
|
|
|
|
Code examples below:
|
|
|
|
### An example of a flowchart
|
|
```
|
|
graph TD;
|
|
A-->B;
|
|
A-->C;
|
|
B-->D;
|
|
C-->D;
|
|
```
|
|
|
|
### An example of a sequence diagram
|
|
```
|
|
sequenceDiagram
|
|
participant Alice
|
|
participant Bob
|
|
Alice->John: Hello John, how are you?
|
|
loop Healthcheck
|
|
John->John: Fight against hypochondria
|
|
end
|
|
Note right of John: Rational thoughts <br/>prevail...
|
|
John-->Alice: Great!
|
|
John->Bob: How about you?
|
|
Bob-->John: Jolly good!
|
|
```
|
|
|
|
