This example shows a hierarchical dataset with nested nodes (A1, B1, C1–C3, B2) displayed as a circle-packing layout, where each node’s bubble size reflects its numeric value. The code uses D3’s `d3.pack()` and `d3.hierarchy()` to compute the layout, with `rootNode.sum()` summing child values for sizing. An SVG canvas is created and sized to the container, and descendant nodes are selected for rendering. The visualization relies on D3 7.8.5 and the `index.js` module exports a `main` function that drives the layout generation and SVG setup.

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.

Fork of Pack Layout

This example visualizes a hierarchical dataset using D3’s pack layout, rendering circles for nodes and text labels for leaf values. The code builds a tree from an inline JavaScript object, sums leaf values with `root.sum()`, and applies a `d3.pack()` layout with a 300×300 size and 10-pixel padding. Each descendant is drawn as an `indianred` circle with white strokes and centered text, positioned via `transform` attributes. The SVG canvas is 960×500 units, and styling comes from an external CSS file.

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.

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.

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.

Basic Circle Pack

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.

Exercise 4(c)

This example shows a circle-packing visualization of a hierarchical dataset, where the size of each circle represents the summed value of its leaf nodes. The code uses `d3.pack()` with a padding of 20 to create non-overlapping circles within a 300x300 area, rendering them as red, semi-transparent SVG circles with white strokes. Leaf nodes display their names as centered white text, while parent nodes remain unlabeled. The data is a hardcoded JSON object with nested children, and the layout is computed by calling `rootNode.sum()` and `packLayout(rootNode)`.

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.
