Our Radial visualizations place photos along a circle using upload dates, geographic coordinates, or visual attributes. One parameter controls the angle (position along the perimeter); another parameter controls the radius (how far a photo is from the center). These compact visualization forms enable us to explore the data on multiple dimensions, presenting, for example, the images organized by their visual attribute (hue, brightness, texture, etc.) and by when and where they were taken – all in a singular visualization. Radial visualizations are particularly useful for studying temporal changes (time is mapped into angle).
