sketchviz is a handy tool:
|
||
|
|
|

|
||
|
|
|
||
|
|
Here is the dot notation for the locations in horses on the brink:
|
||
|
|
|
||
|
|
```
|
||
|
|
graph {
|
||
|
|
rankdir = LR
|
||
|
|
|
||
|
|
s [ label = "Stables" ]
|
||
|
|
t [ label = "Racetrack" ]
|
||
|
|
p [ label = "Pasture" ]
|
||
|
|
v [ label = "Vet" ]
|
||
|
|
w [ label = "The Old Watering Hole" ]
|
||
|
|
|
||
|
|
w -- p -- s -- t
|
||
|
|
s -- v
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
in vim you can visually select the lines and
|
||
|
|
|
||
|
|
```
|
||
|
|
:w !neato -Tsvg > graph.svg`
|
||
|
|
```
|
||
|
|
|
||
|
|
to create the image.
|
||
|
|
|
||
|
|
(neato is a good "spring loaded" layout engine for non directional graphs)
|
||
|
|
|
||
|
|
or if you want to replace the lines with svg,
|
||
|
|
visually select the lines and
|
||
|
|
|
||
|
|
```
|
||
|
|
:!neato -Tsvg
|
||
|
|
```
|
||
|
|
|
||
|
|
I'll do this, copy the resulting svg to a buffer, and then `u` to undo
|
||
|
|
so I can paste the svg somewhere in the document while retaining the original dot info.

if you install `graph-easy` from CPAN then you can use a limited subset of dot to make unicode box art!
|
||
|
|
|
||
|
|
|
||
|
|
```
|
||
|
|
[ The Old Watering Hole ] -- [ Pasture ] -- [ Stables ] -- [ Racetrack ], [ Vet ]
|
||
|
|
```
|
||
|
|
|
||
|
|
visually select and:
|
||
|
|
|
||
|
|
```
|
||
|
|
:!graph-easy --as=boxart
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
```
