ScienceNitrogen cycle — fixation, nitrification, denitrification
The full soil–plant–atmosphere nitrogen cycle: biological and industrial fixation into ammonium, the two-organism nitrification chain through nitrite to nitrate, plant uptake and ammonification back from litter, and the two loss paths — nitrate leaching to groundwater and denitrification to N₂ and N₂O.
ScienceCarbon cycle — flux through a temperate forest
One year of carbon in a mature temperate stand, with every flux in g C m⁻² yr⁻¹ and the budget closing: gross primary production of 1500, half of it respired straight back by the trees, 550 respired by soil decomposers, and the 200 left over as net ecosystem production — the number that decides whether the stand is a sink.
ScienceCatchment hydrology — rainfall to river discharge
A 120 km² upland catchment routed from rain gauge to gauging station: interception and evapotranspiration, the infiltration threshold that decides between overland flow and throughflow, percolation to an unconfined aquifer, and the baseflow that keeps the river running — with P = Q + E + ΔS closing at 1400 = 950 + 450.
ScienceSpaghetti — Aircraft Turnaround, Stand 14
A narrowbody turnaround measured across an 80-metre stand: four ground-handling crews cover 516 m over 24 legs, and the 26 crossings mark every place where baggage, catering and refuelling are working the same apron at the same time.
Spaghetti diagramSpaghetti — Construction Site Logistics
A morning on a 96-metre housing plot: a groundworker, a steel fixer and a labourer cover 855 m over 27 legs between the gate, the laydown area, the mixer and block C, with the store-to-skip haul walked four times.
Spaghetti diagramDecision Tree — Wildcat Well: Seismic, Drill or Farm Out
An exploration decision with an information option: 3-D seismic at $350k splits the prospect into closed-structure and no-closure posteriors, after which the tree drills on closure and farms out otherwise — worth $1,816k against $1,280k for farming out blind and $980k for drilling blind. Illustrative values.
Decision treeDaily Rainfall — Upland Weather Station, 2025 (mm)
A year of 09:00–09:00 rain-gauge totals from an upland station: 1,078 mm across 200 wet days, wetter from October to February, and the October named storm standing out as the wettest day at 61.4 mm. Shading is relative to that storm day, so most ordinary wet days sit in the lighter bands. Illustrative values.
Calendar HeatmapChoropleth — Unemployment Rate by US State (annual average)
Annual-average unemployment rate for all 50 states on the US hex atlas, from 1.9% in SD to 5.6% in NV: the Plains and northern New England are tight labour markets, while Nevada, California and the industrial Midwest run highest. A sequential ramp suits a rate with no meaningful midpoint. Illustrative values.
Choropleth (GIS)Choropleth — Battery-Electric Share of New-Car Registrations by State
Share of new light-duty registrations that are battery-electric, for all 50 states: CA leads at 25.3% and MS trails at 1.4%, an eighteen-fold spread that tracks charging density, state incentives and the West Coast's zero-emission mandates. Illustrative values.
Choropleth (GIS)Choropleth — Renewable Share of Electricity Generation, World
Share of each country's electricity generated from renewables (hydro, wind, solar, bioenergy, geothermal) across 45 countries on the world hex atlas: hydro-rich ETH, NOR and BRA sit near the top, while the Gulf producers and Algeria generate almost entirely from gas and oil. Generation share, not capacity share. Illustrative values.
