Automatic Text Sizing

Automatic Text Sizing

A circle-packing diagram shows the hierarchical Flare dataset as leaf nodes only, with each circle’s size proportional to its value. When a node is hovered, its circle turns orange. Text labels are automatically resized to fit within each circle using D3’s `getComputedTextLength` method, scaling the font size so that longer names shrink to remain readable. The visualization uses `d3.layout.pack` and SVG rendering in D3 v3, with data loaded from a JSON file.

Automatic Text Sizing

A circle-packing visualization displays hierarchical data from a JSON file as nested circles, with each leaf node labeled by its name. The text size adjusts automatically to fit within each circle's diameter, using SVG text elements and a font-size calculation based on the circle's radius and the text's computed length. D3 v3's layout.pack positions the circles, while the code uses this.getComputedTextLength() to scale labels appropriately.

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`.

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.

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.

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

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.

Improved Circle Packing

This visualization uses D3 4.0’s improved circle-packing layout, which computes the smallest enclosing circle for each node to fit circles more tightly than earlier versions. The example displays the hierarchical Flare JSON dataset, with circle size proportional to leaf values and color distinguishing top-level branches. It renders directly to a Canvas element via the d3 pack layout, avoiding SVG’s DOM overhead. The code also includes a bundled d3-xhr library for asynchronous data fetching.
