d3dataMechanism Group
This example demonstrates how D3.js version 5 manages dynamic data updates in a group visualization, showing a fruit bowl where apples and lemons appear, change, and disappear over time. The code uses D3's `select`, `selectAll`, `enter`, `merge`, `exit`, and `transition` APIs to animate the creation, modification, and removal of SVG circles and text elements within groups. A sequential timer modifies the fruit array, triggering re-renders that update the bowl's contents, with color and radius scales mapping fruit types to visual properties.
