This example demonstrates a circle packing visualization that encodes hierarchical data as nested circles, where the area of each circle represents a numeric size value. The visualization shows a dataset of car acquisition and trading history, with parent-child relationships defined by the CSV structure. The implementation uses d3.v4's `d3.stratify` to process the tabular data, `d3.hierarchy` with a size summation function to compute the tree structure, and `d3.pack` to generate the circle layout. Circles are rendered as SVG elements with white strokes and semi-transparent blue fills.

Simple Circle Pack (d3 v4; CSV; 50 Lines)

This circle packing visualization uses a hierarchical treemap-style layout to display car ownership data from a CSV file. It presents nested circles representing categories like "cars," "owned," and "traded," with leaf nodes sized according to their numerical values. The visualization uses d3.stratify() to build the hierarchy from the flat CSV, d3.hierarchy() with a sum aggregation to compute node sizes, and d3.pack() to calculate circle positions and radii. Fifty lines of code render the result as semi-transparent SVG circles with white strokes on a fixed 300×200 canvas.

Circle-Packing

This example visualizes a hierarchical dataset as a circle-packing layout, where each leaf node is a circle sized by its value and nested groups are represented by larger containing circles. It shows the structure of a module tree from a CSV file, with color indicating depth and text labels clipped to leaf circles. The code uses `d3.stratify` to build the hierarchy from flat data, `d3.pack` for layout, and `d3.scaleSequential` with the `interpolateMagma` color scheme. Hovering highlights a node and all its ancestors via `d3.selectAll` with the `node--hover` class, rendered as SVG elements in a `<g>` container.

D3 v5 Circle-Packing

This visualization shows a hierarchical dataset as nested circles, with each circle’s size encoding a numeric value and its color representing depth in the tree. Built with D3 v5 and rendered as SVG, it uses `d3.stratify` to convert the tabular flare.csv data into a hierarchy, `d3.pack` for layout, and `d3.scaleSequential` with `d3.interpolateMagma` for coloring. Hovering highlights a node and its ancestors via the `mouseover` and `mouseout` events.

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.

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.

Circle-Packing II

This example visualizes a flat dataset of names and values using a circle-packing layout, where each person’s name appears as a separate circle. The visualization shows the hierarchical structure of the data through nested circles, with each circle’s size proportional to its value, though all values are equal here. The code uses the d3.pack layout to compute circle positions and radii, then appends SVG circles and text labels with clip paths to keep text within the circles. Data is loaded from a CSV file via d3.csv, and the hierarchy is built with d3.hierarchy and .sum().

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.

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.
