This interactive visualization displays a hierarchical circular packing diagram of the Flare software project's class structure, where nested circles represent parent-child relationships and their sizes encode the relative code volume. Built with D3.js v4 within a React framework, the SVG-based animation supports zooming and panning through the `d3.pack` layout algorithm. The visualization uses smooth transitions via `d3.transition` to animate between hierarchy levels, with color gradients applied based on depth using `d3.scaleLinear`. Users click on circles to explore the tree, while labels fade in and out to show only the currently focused level.

This interactive visualization uses a circular packing layout to display the hierarchical structure of the flare dataset, with nested circles representing categories and their sub-items sized by a numeric value. Clicking a circle zooms into that node, smoothly animating the view through a tween on the interpolateZoom function while adjusting label visibility and opacity for the new focus. The SVG is rendered with D3 v4, using the d3.pack layout and d3.hierarchy API to compute circle positions, and a linear color scale with HSL interpolation to encode depth. The code is built as a React component, though the visualization itself relies on direct DOM manipulation through D3 selections.

This interactive visualization uses a circular packing layout to display a hierarchical dataset from the file `flare.json`. The code employs D3.js v4, React, and SVG with animation, leveraging `d3.hierarchy` to aggregate leaf sizes and `d3.pack` to position circles. Clicking on a node triggers a smooth zoom transition via `d3.transition` and `interpolateZoom` to focus on that subtree, while text labels fade in and out based on parent relationships.

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.

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.

Fork of D3 v5 Circle Packing from Observable

This example shows a circle packing visualization of the Flare software package hierarchy, with nested circles representing the hierarchical structure and size of each node. The visualization uses a sequential color scale with the interpolateMagma colormap to encode depth, and each leaf node displays its name text clipped to the circle boundary. The code is built with D3 v5 and uses the d3.pack, d3.hierarchy, and d3.scaleSequential APIs, loading data from the @observablehq/flare module. Circles are rendered as SVG circles, with hover states and tooltips showing the full ancestor path and value.

Fork of D3 v5 Circle-Packing

This D3 v5 circle-packing visualization displays the hierarchical structure of the Flare software system, using circle size to represent the number of metrics for each module. The graph is built from a CSV file using `d3.stratify()` and `d3.pack()`, with node depth encoded through the `d3.scaleSequential(d3.interpolateMagma)` color scale. Circles are rendered as SVG elements, with clip paths and tspan text for leaf labels, while hovering highlights the ancestor chain via the `node--hover` class.

Fork of D3 v5 Circle-Packing Testing

This visualization shows a circle-packing layout of the Flare software package’s class hierarchy, using nested circles to represent the data’s hierarchical structure. The code loads data from `flare.csv` with `d3.csv`, processes it with `d3.stratify`, and computes the layout using `d3.pack`. Circles are colored by depth using `d3.scaleSequential` with the magma interpolator, and the visualization is rendered as SVG. Hovering highlights a node’s ancestors by toggling a `node--hover` class.

Fork of D3 v5 Zoomable Sunburst

This visualization shows the Flare software package’s class hierarchy as a zoomable sunburst. The circular radial layout displays hierarchical partitions, where each ring represents a depth level and each arc’s size corresponds to the node’s value. Clicking on any arc animates the view, re-centering and rescaling the chart around that node, while a circle at the center returns to the root. The code uses d3.hierarchy, d3.partition, d3.arc, and transition.attrTween on SVG paths, with data loaded via the @observablehq/flare module and color scales built with d3.scaleOrdinal and d3.interpolateRainbow.
