Worked examples

Each of these is a real run: the pipeline picked the columns, shaped the rows and chose the form. Open the trace to see what it decided and why.

Petal length against petal width, by species

The classic result: two of the three species separate cleanly on petals alone, and the pair that overlaps is the pair that always overlaps.

Iris: 150 rows, 5 columns. the two petal measurements and the species label.

Shaping the data6 ms

150 rows in, 150 out across 3 columns. The classic result: two of the three species separate cleanly on petals alone, and the pair that overlaps is the pair that always overlaps.

scatter. Two measures, a categorical split, no time: a scatter.

Mean sepal length by species

Three groups, one measurement: the comparison the question asks for is a ranking, so it is drawn as one.

Schema

5 columns, typed as the pipeline sees them — which is how it knows what can go on a time axis and what can be summed.

Column	Type	Example
sepal_length_cm	number	5.1
sepal_width_cm	number	3.5
petal_length_cm	number	1.4
petal_width_cm	number	0.2
species	text	setosa
