solar family
This animated visualization shows the relative sizes of the Sun, planets, and Pluto as scaled circles, with distances between them deliberately not to scale. Each body appears sequentially via a staggered fade-in transition, labeled below its circle, and colored by characteristic hues. Built with D3.js, it uses `select`, `transition`, and `easeLinear` to animate circle radii and label opacity over two-second and half-second durations. Planet radii and colors derive from Wikipedia data on gravitationally rounded objects, while labels position dynamically based on each circle’s scaled radius.
