# Mermaid Ishikawa Diagram Cheat Sheet

One problem, and the causes under it.

## The problem and its causes

The first line is the problem. The lines under it are the causes, and the indentation is the bone.

```mermaid
ishikawa-beta
    Blurry photo
    Camera
        Out of focus
        Shutter speed too slow
    Environment
        Too dark
```

## Grouping the causes

A cause one level in is a group, and the lines under it are the reasons for that cause.

```mermaid
ishikawa-beta
    Blurry photo
    Camera
        Out of focus
        Dirty lens
    User
        Shaky hands
```
