Each disc is one study. Discs stack from the bottom of their outcome column, so column height reads as evidence volume. Colour reads as direction of effect. Four aligned discs of one colour mark a run of consistent findings.
Forty-eight wards across the two boroughs, tracked over five years. The map shades healthy life expectancy; the circles show new homes completed each year. Move through the timeline to see how building and health have shifted together, ward by ward.
Every line is a structural determinant of health. Every station is a project delivered in Lambeth or Southwark. The vertical axis is the participation ladder, so a line climbing the map is power moving toward residents, and a line falling is power moving back. Interchanges are projects where two determinants were addressed by one community coalition.
