This example demonstrates a simple animated face made from D3.js circles, where fruits represent facial features. It shows five apples initially, then removes one apple and changes another into a lemon, updating the circle sizes and colors accordingly. Using D3 v5 APIs like `d3.range`, `d3.scaleOrdinal`, and selection methods like `selectAll`, `enter`, `merge`, and `exit`, it dynamically redraws the SVG circles in response to data changes. The visualization uses ordinal color and radius scales to map fruit types to red or yellow hues and varying sizes.
