A circle-packing visualization displays a hierarchical dataset as nested circles, with buttons to add or remove data nodes from the DOM. Using D3 v5’s `d3.pack` layout and `d3.hierarchy`, the SVG renders each node’s size proportional to its value. Clicking a circle zooms via a tween that interpolates the view, while mouseover and mouseout events add or remove stroke outlines. The code uses D3 selections, transitions, and the `transition.tween` API for smooth animation.

Basic Circle Pack 2 - working

This example shows an interactive circle packing visualization of hierarchical data. Circles represent nodes in a tree, with nested circles indicating parent-child relationships, and clicking a circle zooms to expand that branch. The visualization uses d3.pack for layout and d3.hierarchy with sum and sort for data preparation. Add and remove buttons trigger rendering, each creating a new group of circles with different data. The code uses d3.scaleLinear with interpolateHcl for color encoding, d3.interpolateZoom for animated transitions, and SVG for rendering with click, mouseover, and mouseout event handlers.

A hierarchical circle-packing visualization displays nested data as clustered bubbles, with zooming and panning via mouse clicks. The demo uses D3.js v5 to construct the SVG layout, apply an HSL color scale by depth, and animate transitions between hierarchy levels using `transition` and `interpolateZoom`. Buttons add or remove data nodes, while the pack layout is generated with `d3.pack` and `d3.hierarchy`. The dataset is hardcoded from a “flare” file structure.

Fork of Basic Circle Pack

A fork of the basic circle pack example demonstrates hierarchical data visualization using d3.pack, where circles represent nested nodes and are colored by depth using a linear scale. The view animates between zoom levels via d3.interpolateZoom, triggered by clicking circles or the background. Buttons allow adding and removing data, though the specific data mutation logic is not shown. The visualization renders in SVG with smooth transitions, and labels appear only for the current focus node's children.

Circle Packing

This visualization displays a hierarchical dataset as nested circles, using area to represent the number of descendants in each node. Color distinguishes between constrained and unconstrained nodes, with constrained items shown in gray and unconstrained ones in blue. The layout is computed using D3’s `pack` algorithm, which positions circles within a viewport sized to the browser window. Data is loaded from `data.json` via D3’s `json` function, then processed with `hierarchy` and rendered as SVG `<circle>` elements, with white strokes providing visual separation between adjacent circles.

D3 Pack Layouts

This example demonstrates a D3 pack layout, which visualizes hierarchical data as nested circles. The dataset defines a tree with a root node, two levels of children, and leaf nodes that carry numeric values. Using `d3.hierarchy` and `d3.pack`, the code computes circle positions and radii so that parent circles encompass their children proportionally to summed values. The visualization renders each node as a semi-transparent circle with a white stroke, and labels only the leaf nodes. The SVG is dynamically sized to fit the container, and nodes are positioned via CSS transform translations.

Pack Layout

This example demonstrates a circular pack layout for hierarchical data using d3.pack, showing nested circles that represent parent and child nodes with sizes proportional to their values. A small dataset with three levels of hierarchy is rendered as SVG circles with semi-transparent indianred fills, white strokes, and text labels only on leaf nodes. The code uses d3.hierarchy and the pack layout to compute positions and radii, then appends transformed groups for each descendant.

Circle Packs

A circle-packing visualization displays a horizontal row of fruit icons, each rendered as a colored circle with a text label, inside a rounded rectangular bowl. A color scale and a radius scale map fruit types to distinct hues and sizes. Users can add or remove apples via buttons, triggering enter, update, and exit selections that animate the circles through D3’s data join. The example uses D3 v5 with SVG, ordinal scales, and explicit selection methods to manage dynamic data.

dynamic pack

This interactive pack layout uses a circle-packing algorithm from D3 v4 to represent a hierarchical tree. Users can drag nodes to merge them, right-click on the canvas to add new nodes, or right-click on a node to delete it along with its descendants. The underlying `rData` tree object updates dynamically, and all changes are rendered as animated SVG elements. The implementation relies on custom `d3.drag` behaviors and the `d3.pack` layout.
