This animated visualization displays the planets of the Solar System, with relative sizes scaled proportionally (though distances are not). The Sun and planets appear as solid circles with labels, using data from Wikipedia’s list of gravitationally rounded objects. The code leverages D3’s `select`, `transition`, and `easeLinear` to animate the circles growing and fading in sequence. Each planet’s radius and position derive from the imported data array, with SVG circles and text elements styled in black space with white labels.
