<markdown> # Draw Diagrams With Markdown

Typora supports some Markdown extension for diagrams, you could enable this feature from preference panel.

When exporting as HTML, PDF, epub, docx, those rendered diagrams will also be included, but diagrams features are not supported when exporting markdown into other file formats in current version. Besides, you should also notice that diagrams is not supported by standard Markdown, CommonMark or GFM. Therefore, we still recommend you to insert an image of these diagrams instead of write them in Markdown directly.

# Sequence

It is powered by [js-sequence](https://bramp.github.io/js-sequence-diagrams/), which would turn following code block into rendered diagrams:

~~~gfm ```sequence Alice→Bob: Hello Bob, how are you? Note right of Bob: Bob thinks Bob–>Alice: I am good thanks! ``` ~~~


Please refer [here](https://bramp.github.io/js-sequence-diagrams/#syntax) for syntax explanation.

# Flowchart

It is powered by [flowchart.js](http://flowchart.js.org/), which would turn following code block into rendered diagrams:

~~~gfm ​```flow st⇒start: Start op⇒operation: Your Operation cond⇒condition: Yes or No? e⇒end

st→op→cond cond(yes)→e cond(no)→op ​``` ~~~


# Mermaid

Typora also has integration with [mermaid](https://knsv.github.io/mermaid/#mermaid), which supports sequence, flowchart and gantt.

## Sequence

see [this doc](https://knsv.github.io/mermaid/#sequence-diagrams)

~~~gfm ​```mermaid Example of sequence diagram sequenceDiagram Alice->>Bob: Hello Bob, how are you? alt is sick Bob->>Alice: Not so good :( else is well Bob->>Alice: Feeling fresh like a daisy end opt Extra response Bob->>Alice: Thanks for asking end ​``` ~~~  ## Flowchart see [this doc](https://knsv.github.io/mermaid/#flowcharts-basic-syntax) ~~~gfm ​```mermaid graph LR A[Hard edge] -->B(Round edge) B --> C{Decision} C -->|One| D[Result one] C -->|Two| E[Result two] ​``` ~~~  ## Gantt see [this doc](https://knsv.github.io/mermaid/#gant-diagrams) ~~~gfm ​```mermaid Example with slection of syntaxes
