TANK 01

INFLOW

Drops of raw JSON fall through the ceiling and accumulate as a rising histogram in the tank floor. Listen for the gurgle.

note: each drop is a row; bins emerge by the third minute, like silt settling.

{ "id": 8421, "mass": 3.14 }

TANK 02

SCHEMA REEF

A coral built of typed column headers. Each polyp is a field on a thin tether; hover one and it speaks its signature.

note: varchar(255) grows fastest in spring; timestamptz blooms after migrations.

TANK 03

THE PLOT POOL

A wide pool of 84 swimming fish. Each is a row; their (x, y) is a real bivariate datum. Hover ripples; click pins a specimen.

note: this scatter migrates north at dawn.

TANK 04

THE JOIN CHANNEL

Two streams enter from opposite tanks and merge through a glass aqueduct. Toggle to reshape the SQL JOIN flow.

INNER LEFT RIGHT FULL OUTER

note: a FULL OUTER JOIN looks suspiciously like estuarine confluence.

TANK 05

AGGREGATION TRENCH

200 motes sink through the deep glass column and compress into four luminous strata: SUM, MEAN, MEDIAN, P95.

• SUM—
• MEAN—
• MEDIAN—
• P95—

note: the median always sinks last. it is the trench's most patient creature.

TANK 06

ANOMALY TANK

Black glass. A normal distribution drifts as 1,000 dots; the 23 outliers beyond 3σ bioluminesce in violet.

note: outliers are seasonal. they appear after deploys.

TANK 07

SEDIMENT ARCHIVE

Decommissioned graphs settle as fossilized layers. Click a stratum to expand its archived chart.

APPENDIX

CHART-AS-FISH BESTIARY

Twelve species, each a chart primitive made flesh. Latin binomials and field-note habitats follow the marine biologist's pencil.
