Crafting Visual Stories with Data.
aq = require("arquero")
data = aq.fromJSON(raw)
Inputs.table(data)
Derive
Create a new columns
Inputs.table(derivedData)
recodeObject = ({
top: 1,
center: 0,
bottom: -1
})
derivedData = aq
.from(data)
.params({ recodeObject })
.derive({
// Column Name: function to compute the values of the new column
// idPlus: Function (take the value of id and add one)
idPlus: (d) => d.id + 1,
// sidePlus: (d) => d.side map this transformation given by the recode object
sidePlus: (d) => aq.op.recode(d.side, recodeObject)
})
// Long form Function
function add(d, $) {
return d.id + $.id;
}
// Short form function (Arrow Function)
add1 = (d, $) => d.id + $.id
// No name function (Anonymous Function)
(d, $) => d.id + $.id
add({ id: 2 }, { id: 3 })
add1({ id: 2 }, { id: 3 })
Purpose-built for displays of data
Observable is your go-to platform for exploring data and creating expressive data visualizations. Use reactive JavaScript notebooks for prototyping and a collaborative canvas for visual data exploration and dashboard creation.
