Forked from 12.a - fruit bowl - d3 update pattern - dataviz 2018

A fruit bowl visualization demonstrates the D3 update pattern with nested elements, showing apples and lemons as circles in a bowl that changes over timed intervals. The code uses d3.scaleOrdinal for colors and radius mapping, with d3-selection’s enter, merge, and exit methods to handle dynamic data updates. An SVG renders the bowl as a rounded rectangle, while each fruit is a group containing a circle and text label. The example includes a deliberate data mutation where an apple becomes a lemon, illustrating how the update pattern reuses existing DOM nodes efficiently.

12.c - fruit bowl - d3 update pattern, nested elements w/ transitions - dataviz 2018

A fruit bowl visualization demonstrates the D3 update pattern for nested elements with transitions. The SVG scene shows apples and lemons positioned inside a bowl, with fruits entering, exiting, and changing type over time. Using d3.select, d3.range, and d3.scaleOrdinal, the code manages enter, update, and exit states via selection.transition().duration(), animating circle radii, fill colors, and text opacity. The example uses fruitGroups.select('circle') and fruitGroups.select('text') to handle sub-elements independently, with Math.random() generating unique IDs for data tracking.

12.a - fruit bowl - d3 update pattern - dataviz 2018

Balls representing apples and lemons enter, update, and exit a horizontal row on an SVG canvas, using the D3 v7 data join pattern. The example demonstrates the enter-merge-exit sequence with `selection.data()`, `.enter().append('circle')`, `.merge()`, and `.exit().remove()`, animating circle radius and x-position via `.transition().duration()`. Colors and radii map ordinal scales (`scaleOrdinal`) for fruit types, while JavaScript `setTimeout` calls drive state changes. SVG circles render the fruit bowl, with transitions smoothly resizing and repositioning elements.

Bowl of Fruit - Nested Update Pattern

A bowl of fruit demonstrates the nested update pattern in D3 v6, where apples and lemons are rendered as SVG circles and labels inside a rounded rectangle bowl. The code uses `scaleOrdinal` for color and radius mappings, and the `enter`/`merge`/`exit` selections to handle data changes. Over timed intervals, fruits are removed and one apple is replaced with a lemon, showing how the visualization updates smoothly.

Bowl of fruit - General Update Pattern

This example demonstrates the D3 general update pattern using a bowl of fruit rendered with SVG shapes. Five apples appear initially, then the visualization updates twice: first removing two apples, then changing one apple to a lemon. The code uses `d3.scaleOrdinal` for color and radius scales, with enter, update, and exit selections managing circles and text elements. The fruit bowl is drawn as a rounded rectangle, and the update functions use `merge()` and `.exit().remove()` to handle data changes.

Bowl of fruit - General Update Pattern

A bowl of fruit demonstrates the D3 general update pattern, showing apples and lemons rendered as colored circles that are added, removed, and changed over time. The visualization uses d3.select, data joins, and enter/merge/exit selections in the fruitBowl function, with d3.scaleOrdinal mapping fruit types to colors and radii. The SVG output updates through three timed transitions, first removing an apple, then changing an apple to a lemon, and finally filtering out another apple.

Bowl of fruit, general update Pattern

This example demonstrates the general update pattern in D3.js, showing a bowl of fruit as circles that change over time. Initially five apples appear, then one is removed, another changes to a lemon, and a second apple is eaten. The visualization uses d3.scaleOrdinal for color and radius mapping, with enter, merge, and exit selections to handle dynamic data updates. Rendered as SVG in a React framework with d3.v5, the code also includes a static bowl shape drawn as a rounded rectangle.

Bowl of fruit General Update Pattern 2

A bowl of fruit demonstrates the general update pattern in D3, showing how apples and lemons are added, removed, and modified in an SVG visualization. The code uses D3 v6 with `selection.enter`, `selection.merge`, and `selection.exit` to handle data joins, while `scaleOrdinal` maps fruit types to colors and radii. Over timed intervals, the example pops apples from the array, replaces one apple's type with a lemon, and filters out another, with each change re-rendering the bowl and updating the circle and text elements accordingly.

Bowl of Fruit- General Update pattern

This example demonstrates the D3.js general update pattern by animating a bowl of fruit, where apples are eaten, replaced with lemons, and removed over time. It uses D3 selections with enter, merge, and exit methods to manage dynamic data binding, rendering SVG circles and text elements via a reusable `fruitBowl` function. The visualization employs `d3.scaleOrdinal` to map fruit types to colors and radii, with the data driven by timed `setTimeout` callbacks that modify a hardcoded fruits array.
