Charts about the things we teach, built from public data.
Some we made ourselves from named datasets. Some are diagrams of the ideas we use at work. A few are famous old charts we rebuilt in code to see how they were made, and there's a shelf of newer work by other people worth your time.
Same numbers, two y-axes. Start a bar chart anywhere but zero and you can invent a trend or hide one. Every chart here starts at zero.
Principle: Tufte's "lie factor". A graphic should not say more, or less, than the data.

The ideas behind the numbers
Numbers tell you what happened. These are some of the models we use to ask why, and what to do next.
Arnstein's Ladder of Participation
Not all "participation" is equal. Sherry Arnstein's 1969 ladder climbs from token consultation to genuine citizen power — a staple of our governance and MEL teaching.
The Results Chain & the Attribution Gap
Every theory of change runs from inputs to impact. The hardest gap to cross — and to prove — is the one between what a programme produces and the change in people's lives.
The Poverty Trap
A reinforcing loop: low income starves savings and investment, which holds down productivity, which holds down income. Breaking any one link is the work of development.
Intersectionality
Disadvantage compounds. Gender, caste and class are not separate problems to add up — they intersect, and the overlap is where the deepest exclusion sits.
The Systems Iceberg
The events we react to sit above the waterline; the patterns, structures and mental models that produce them sit below. Lasting change works underwater.
