MarkChart - Mermaid Editor 4+

MarkChart is designed exclusively for previewing and editing Mermaid diagrams. Start with a built-in template to instantly create sequence diagrams, state diagrams, flowcharts, and more. Or begin with a blank document to write your own diagram from scratch. MarkChart can also be used in combination with an external editor, diagrams automatically update when changes are made.

Mermaid is a Markdown-inspired text syntax to define diagrams. MarkChart will render a nice looking sequence diagram if you write the following text in your Markdown documentation:

```mermaid
sequenceDiagram
Alice->>John: Hello John, how are you?
John-->>Alice: Great!
Alice-)John: See you later!
```
