What are the chances to align such a pleasant mirror-inverted symmetry in the positioning of these spheres together? Not many according to Lucas Isei’s script: – attr(‘cx’, d => (d.x + Math.random())), attr(‘cy’, d => (d.y + Math.random())) -. For good measure, I used Andy Burnett zoomable tree-map as a backdrop. Treemapping is a method for displaying hierarchical data using nested figures. Fitting!
