Simple demonstration of [Arquero](https://uwdata.github.io/arquero/) using Allison Horst's [Palmer Penguins](https://allisonhorst.github.io/palmerpenguins/) dataset.

If you want to use inputs in an arquero query, you can use the `params` method of table.
Below is a simple example of filtering a dataset by the values provided.
```{ojs}
//| panel: input
viewof bill_length_min = Inputs.range(
[32, 50],
{value: 35, step: 1, label: "Bill length (min):"}
)
viewof islands = Inputs.checkbox(
["Torgersen", "Biscoe", "Dream"],
{ value: ["Torgersen", "Biscoe"],
label: "Islands:"
}
)
```
```{ojs}
penguins
.params({
blm: bill_length_min,
i: islands
})
.filter((d, $) => op.includes($.i, d.island) && d.bill_length_mm > $.blm)
.view()
```
