Definition
Why it is in scope
A human-made data visualization that maps quantitative or positional data onto a polar coordinate system aligned with the sun's path — showing solar position, insolation, shadow casting, or seasonal light patterns. Used in architectural design, agricultural planning, and renewable energy siting to visualize how sunlight interacts with terrain, buildings, or land over the course of a day or year.
