Circles Part3
✓ Published1🌍 Public
Three face-like clusters of circles are grouped and then re-sorted into rows by color when a button is clicked. The visualization uses React state to manage the SVG circles, with D3’s `selectAll`, `data`, and `transition` APIs to animate the `cy` attribute over one second. A `d3.nest` key operation groups circles by their color property, and the resulting groups trigger rendering of text labels. The example is built with React 16.9, D3 v5, and renders via SVG.
