This visualization shows hourly solar analemmas, the figure-eight paths traced by the Sun’s position at each fixed time of day, as seen from San Francisco during 2014. The background is a stereographic projection of the celestial sphere, rendered with d3.geoCircle, d3.geoGraticule, and d3.geoPath, with compass labels and altitude ticks. Twenty-four red paths, one per hour, are computed by the solar-calculator package and projected via a custom flippedStereographic function. The SVG output uses D3 v4 selections and data joins over hourly timestamps.
