Bowl of Fruit - Feneral Updata Pattern
A bowl of fruit demonstrates the D3 general update pattern, showing how data joins manage enter, update, and exit selections as items are added, removed, or modified. Five circles represent apples and lemons, with color and radius scales mapping fruit types to visual properties. Using d3.selectAll, .merge(), and .transition(), the example animates new apples growing from radius zero, existing fruits shifting positions, and removed fruits shrinking away. The code runs three timed updates via setTimeout, eating apples, swapping one for a lemon, and filtering another, all rendered as SVG transitions over one-second durations.
