Set up a file like this, called `troubleshooting.txt`.
> [ Is there an IP address? ] -- no --> [ Check NIC driver, dmesg ]
>
> [ Is there an IP address? ] -- yes --> [ Can you ping the router? ]
>
> [ Can you ping the router? ] -- no --> [ Check cables, router, and switches ]
>
> [ Can you ping the router? ] -- yes --> [ Can you ping a DNS address? ]
>
> [ Can you ping a DNS address? ] -- no --> [ Trying pinging 8.8.8.8 ]
>
> [ Can you ping a DNS address? ] -- yes --> [ Traceroute ]
Then translate it with:
```sh
graph-easy troubleshooting.txt --as boxart
```
```

Many options allow different displays.
Try placing this in a file:
> [ One ] { fill: seagreen; color: white; } -- label --> [ Two ] { shape: triangle; }
>
> [ One ] => { arrow-style: closed; } [ Three ] { border-style: none; }
>
> [ Five ] { fill: maroon; color: yellow; } <=> [ Three ]
>
> [ One ] .. Test\n label ..> [ Four ]
>
> [ Three ] { border-style: dashed; }
>
> .. Test\n label ..> { arrow-style: closed; } [ Six ] { label: Sixty\n Six\nand\nsix; }
>
> [ Three ] <-- Test label --> { arrow-style: closed; } [ Six ]
>
> [ Eight ] .. [ None ] { shape: none; fill: red; color: brown; }
>
> [ no Network ] --> [ Is there an IP address? ]
> [ Little Group: o]
