What would be the easiest way to create a [spider plot](http://gnuplot.sourceforge.net/demo_5.4/spiderplot.html) (or radar/star plot) from an org-mode table using `org-plot/gnuplot`?

The [org-plot](https://orgmode.org/manual/Org-Plot.html) docs suggests it should be possible using a `script:` option but it's not clear to me how the table columns can be converted into arrays in a gnuplot script (using this [example code](http://gnuplot.sourceforge.net/demo_5.4/spiderplot.7.gnu) as a starting point)

The input would look something like this...

```
#+PLOT: title:"spiderplot" set:"output './img/spiderplot.png'" script:"spiderplot.gp"
#+TBLNAME: three-fold
| Array1 | Array2 |  Array3 |
|     15 |     25 |      30 |
|     75 |     25 |      35 |
|     20 |     50 |      55 |
|     43 |     50 |      55 |
|     90 |     75 |      80 |
|     50 |     50 |      25 |

```

and produce an image something like this...
