Forked from Bowl of Fruit - General Update Pattern Special Cases

This animated visualization demonstrates the special-case update patterns in a butterfly graph, a structure used in Cooley–Tukey FFT algorithms. It shows how nodes and their connections evolve across logarithmic stages, with bit-reversed input labels and DFT output labels. The D3.js code builds the graph programmatically, computes node positions as percentages, and draws smooth Bezier curves between parent–child pairs. Hovering a node highlights its entire dependency chain—including connected circles, paths, and text—by transitioning their fill and stroke colors to steelblue, while non-hovered elements fade to gray. The visualization uses D3’s selection, transition, and event-handling APIs to animate these interactive highlights, with the SVG scaled via a viewBox.

Fork of Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern for a d3 partition layout, rendering a sunburst diagram with animated transitions. The visualization uses d3.arc to generate both the visible arcs and invisible mouse-tracking arcs, with d3.partition and d3.hierarchy processing the hierarchical CSV data. Interactive mouseenter, click, and mouseleave events are bound to the invisible arcs, while the visible arcs transition smoothly using d3.transition. The color scheme uses d3.scaleLinear with d3.interpolateHsl to map data values to a red-white-blue gradient.

Fork of Bowl of Fruit - General Update Pattern

A dynamic SVG visualization demonstrates the D3 general update pattern by rendering a changing bowl of fruit. Rows of apple and lemon circles shift position as fruit are removed or transformed over time, with colors and radii mapped via ordinal scales. The code uses D3 v6 with `selection.enter()`, `selection.merge()`, and `selection.exit()` to manage data joins, updating circle and text elements in response to timed JavaScript state changes.

Fork of Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates how D3.js handles updates to a dataset by animating the addition, removal, and modification of elements. It shows a bowl of fruit represented by colored circles with labels, using D3's `select`, `range`, and `scaleOrdinal` functions. The `transition().duration(1000)` API animates radius and text changes as apples are eaten and replaced with lemons, while the SVG and g elements are created and removed through the general update pattern.

Fork of Bowl of Fruit- General Update Pattern with animation

A fork of the Bowl of Fruit example demonstrates the D3 general update pattern for dynamic data changes over time. Five apples render as SVG circles with colored fills and text labels, transitioning through three state changes: removing a fruit, replacing an apple with a lemon, and filtering out another item. Using d3.scaleOrdinal for color and radius, the code binds data to groups, appending and merging enter selections while handling exit removals, with each update triggered by setTimeout calls.

Fork of Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the "general update pattern" special cases in D3 by animating a bowl of fruit. The visualization shows a sequence of changes to a data array—removing the last or a middle element, and updating an item's type—and how the SVG scene updates to reflect them. The code uses `d3.select` and a custom `fruitBowl` function to manage the SVG elements. It relies on `scaleOrdinal` for color and radius mappings, and appended `rect`, `circle`, and `text` elements to render the bowl and fruits.

Fork of Bowl of fruit - General Update Pattern

A demonstration of D3's general update pattern shows a changing bowl of fruit, where apples are removed, replaced by lemons, or eaten over time. The visualization displays each fruit as a circle with a label, using ordinal scales for color and radius to distinguish types. The code applies incremental updates to SVG groups via D3's selection merge and exit methods, orchestrating changes with `setTimeout` calls to trigger sequential state changes. The example is built with D3 v6 and renders to SVG.

Fork of Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern for dynamic data in D3.js, using a bowl of fruit as a visual metaphor. It shows how the chart reacts to changes in a fruit array over time: five apples appear initially, one is removed, one apple changes to a lemon, and another apple is filtered out. The code uses D3’s selection API, including `select`, `selectAll`, `enter`, `merge`, and `exit`, to update SVG elements. It also leverages ordinal and linear scales from D3 to map fruit types to colors and radii.

Fork of Bowl of Fruit - General Update pattern (text)

This example demonstrates the general update pattern in D3.js by animating a bowl of fruit that changes over time. It shows how data joins manage entering, updating, and exiting SVG elements—apples are eaten, one apple turns into a lemon, and positions shift with each render cycle. The code uses d3-scale’s `scaleOrdinal` for color and radius mapping, while transitions animate circle sizes and repositions groups after each state change. Rendered as SVG, the bowl is a static rectangle, and text labels identify each fruit type.
