Kepler’s Tally
Kepler's Tally displays exoplanet systems from NASA's Kepler mission as tiny star systems, each with planets orbiting on circular tracks. Using D3 v3 and SVG, the visualization derives a scale for semimajor axis, planet radius, and orbital period from the CSV data, then renders static orbit rings and CSS3-animated planets. The animation relies on keyframe rotations with vendor-prefixed transforms, and the planet circles use a radial gradient. Systems are sorted by overall radius to create a compact, grid-like overview.
AI-generated descriptionA minimalist variation of Jonathan Corum’s interactive graphic on exoplanets discovered by NASA’s Kepler mission. This version lacks stars, labels, and more, but demonstrates the use of CSS3 for simple declarative animation of orbits.
