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.

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.

Basic Circle Pack - Add or Remove Trees from the DOM

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.

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.

D3 v5 Circle-Packing

This example implements a circle-packing visualization using D3 v5, displaying a hierarchical dataset from the Flare library. The diagram shows a nested arrangement of circles, where each circle represents a data node, with its size proportional to a value and color indicating depth in the hierarchy. Built with D3’s `d3.stratify` and `d3.pack` APIs, it renders to SVG, applying a sequential magma color scale. Interactive mouseover highlights ancestor nodes, while leaf labels are clipped via `clipPath`, and tooltips show the node ID and value.

Layout

This example shows an interactive circular packing diagram where each circle represents a node in a hierarchical dataset, with leaf nodes as white circles and parent nodes colored by depth. Clicking a circle zooms to focus on that subtree, smoothly transitioning the view. Built with D3 v4, it uses the `d3.pack` layout to compute circle positions and radii, and `d3.hierarchy` to process the data from a local `flare.json` file. The visualization is rendered as SVG, with hover highlighting on nodes and a zoom transition that repositions and rescales circles and labels via the `transition` API.

Zoomable Circle Packing

Nested circles represent the hierarchical structure of the Flare visualization toolkit, with each circle’s area proportional to the underlying data value. Clicking a circle smoothly zooms the view to focus on that subtree, while the background color shifts and labels fade in and out during the animated transition. The visualization uses D3 v4’s `d3.pack` layout, `d3.hierarchy`, and `d3.interpolateZoom` to calculate circle positions and drive the zoom animation, rendering the hierarchy as SVG circles and text elements. Data comes from the bundled `flare.json` file.

Untitled

This interactive zoomable circle packing visualization displays the hierarchical structure of the flare.json dataset, with nested circles representing parent and child nodes sized by their numeric values. Users click circles to zoom into deeper levels, with smooth animated transitions between views. The visualization uses D3.js v4’s `d3.pack` layout, `d3.hierarchy`, and `d3.interpolateZoom` to animate the zooming effect, rendered as SVG elements with a linear color scale distinguishing depth levels. Text labels appear and fade based on the current zoom focus.

Store constraining + zoomable pack circle

This zoomable circle packing visualization displays hierarchical data from altData.json using nested circles sized by leaf node values. The chart starts centered on the root node and animates through zoom transitions when clicking child circles, revealing deeper levels of the hierarchy. Built with D3 v5, the code uses `d3.pack`, `d3.hierarchy`, and `d3.interpolateZoom` to calculate layouts and smooth zooming, while transitions update circle radii and label visibility. The SVG rendering uses a color scale to distinguish depths, with click handlers enabling interactive navigation through the tree structure.
