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.

Zoomable Circle Packing

This interactive visualization displays the hierarchical structure of the Flare class library using nested circles, where each circle’s area encodes the size metric from the underlying flare.json dataset. Clicking any circle triggers a smooth zoom transition, bringing that node and its descendants into focus, while clicking again zooms back out. The visualization is built with D3 v4 and rendered as SVG, with hover effects highlighting nodes and labels that adjust dynamically as the hierarchy expands and collapses.

Zoomable Circle Packing

This interactive visualization displays a hierarchical dataset as nested circles, where each circle represents a node and its size corresponds to the node's value. Clicking any circle animates a zoom to that node, revealing its children and hiding unrelated elements. The implementation uses d3.layout.pack for the circle layout and d3.interpolateZoom for smooth zoom transitions. The data comes from the flare.json file, which contains a tree structure with named categories and numeric sizes. The visualization renders with SVG circles and labels, with a color scale applied by tree depth.

Circle Packing

This example visualizes the Flare class hierarchy as an enclosure diagram, using nested circles to represent the structure and size of each node. The visualization uses a circle-packing layout, where each circle’s area is proportional to the numeric value of its corresponding data item, and parent circles enclose their children to reveal the hierarchy. The implementation relies on `d3.pack()` for layout, `d3.hierarchy()` for data aggregation, and renders the result as an SVG with styled circles and labels. The color scheme distinguishes leaf nodes as orange with full opacity, while non-leaf circles are blue and semi-transparent.

Untitled

This visualization shows a zoomable circle packing layout of the Flare software dependency hierarchy, where each node’s area encodes its size value. Clicking a circle zooms to that subtree, smoothly interpolating the view with `d3.interpolateZoom` and animating label opacity and display. It uses `d3.pack`, `d3.hierarchy`, and `d3.scaleLinear` with HCL interpolation, rendering in SVG within a React framework. Data comes from the bundled `flare.json` file.

Circle-Packing

This example visualizes the hierarchical structure of the Flare dataset using circle packing. Each node is represented as a circle, with leaf nodes sized by their value and grouped by their parent categories. The visualization uses D3 v4’s `d3.stratify` to build a hierarchy from the CSV and `d3.pack` to compute the circular layout. SVG circles are colored with a sequential magma scale based on depth, and hovering highlights the ancestors of a node via a CSS class and the `d3.selectAll` method.

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.

Circle-Packing II

This visualization displays a hierarchical bubble chart of the Flare dataset, where each circle’s area encodes a numeric value and its color reflects the data’s grouping structure. Built with D3 v4, the chart uses `d3.pack` to compute non-overlapping circle positions within a fixed canvas, with each node labeled by its class name and tooltip showing the raw value. The SVG rendering applies a clip-path to each node so text remains contained within its circle, and hovering highlights the selected bubble.

Circle-Packing II

A circle-packing visualization displays the hierarchical structure of the Flare dataset, with each node represented as a circle whose size encodes a numeric value. The code uses D3 v4's `d3.pack` layout to compute circle positions and radii, and `d3.hierarchy` to process the CSV data. SVG elements are generated manually, with circle nodes, clip-paths for text labels that split on capital letters, and tooltips showing full paths and formatted values via `d3.format`.
