Three-dimensional wireframe cube rendered in 2.5D perspective (isometric projection) representing the WHO UHC three-dimension model. The three axes are: Population covered (Who — from 0% to 100% of population), Services included (What — from narrow emergency care to comprehensive care), and Direct costs (How much — from 100% out-of-pocket to fully subsidized). An interactive slider controls the size of the shaded volume representing current coverage; the default fills roughly 50% of the cube to represent a middle-income country. Three buttons cycle through preset country profiles: "Low-income country," "Middle-income country," and "High-income country," each adjusting the shaded volume dimensions. Clicking any face of the cube opens an annotation panel explaining that dimension (population coverage, service range, financial protection). A tooltip on hover shows the numerical value for the selected country profile on each axis.
