A treemap visualizes the hierarchical structure of the Flare visualization toolkit, using nested rectangles whose areas encode the `size` value of each node and color to distinguish top-level packages. The chart is built with D3 v3, using the `d3.layout.treemap` API to compute the squarified layout, and rendered as SVG with styled `rect` elements and labels for leaf nodes. Data comes from the bundled `flare.json` file, which contains the toolkit’s package hierarchy and sizes.

AI-generated description

A treemap recursively subdivides area into rectangles; the area of any node in the tree corresponds to its value. This example uses color to encode different packages of the Flare visualization toolkit. Treemap design invented by Ben Shneiderman. Squarified algorithm by Bruls, Huizing and van Wijk. Data courtesy Jeff Heer.

Treemap

A treemap recursively subdivides a rectangle into smaller rectangles, with each node's area proportional to its value, encoding the hierarchical structure and size of the Flare visualization toolkit's packages through both position and color. The visualization includes an interactive radio-button control that toggles between summing leaf sizes and counting leaves, triggering a 750-millisecond transition that animates rectangle boundaries using D3 v4's `d3.treemap` with the `d3.treemapResquarify` tiling algorithm. Rendered as SVG, the code uses `d3.hierarchy`, `d3.scaleOrdinal` with the `schemeCategory20` color palette, and `d3.json` to load the packaged flare.json dataset.

Treemap from bl.ocks.org

A treemap visualizes the hierarchical structure of the Flare data set, with nested rectangles whose areas encode either the size or count of each node. The visualization uses D3’s `d3.treemap` layout with `d3.treemapResquarify` tiling, rendering the hierarchy as an SVG. Animated transitions smoothly reshape the treemap when toggling between the "Size" and "Count" aggregation modes. The color scheme is derived from `d3.schemeCategory20`, and the tooltip displays the node’s path and numerical value.

treemap

This treemap visualizes the Flare software package hierarchy, where each rectangle’s area encodes the relative size of a module (e.g., lines of code or class size). Built with D3 v3, the visualization uses nested rectangles and a categorical color scale to show the hierarchy of top-level categories like analytics, animate, data, and display, with subcategories and leaf nodes nested inside. The layout is generated using d3.layout.treemap, with each node's area proportional to its `size` value. The white borders between cells and the small sans-serif labels maintain readability, making the hierarchical structure and relative magnitudes of the Flare visualization toolkit’s codebase easy to compare at a glance. The visualization is interactive and hoverable.

Treemap

This treemap visualizes the hierarchical structure of the Flare codebase, using rectangular nested cells to represent file sizes and categories. Built with D3.js v4, it uses the `d3.stratify()` and `d3.treemap()` APIs to lay out nodes, with color assigned from a `d3.scaleOrdinal()` palette based on top-level branches. Leaf values from `flare.csv` are displayed inside each cell, while hovering reveals the full path and numeric value. The rendering uses HTML divs positioned absolutely, with nested labels and value text.

A treemap visualizes the hierarchical structure of the Flare data set, with nested rectangles representing leaves sized by their numeric value. The visualization renders using SVG elements and includes an animated transition between two aggregation modes: "Size" and "Count". Built with D3 v4, the code uses `d3.treemap` with the `d3.treemapResquarify` tiling algorithm, `d3.hierarchy`, `d3.scaleOrdinal` for color, and `d3.interpolateRgb` for fading. A 2-second timer automatically triggers the mode change.

Nested Treemap

A nested treemap visualizes the hierarchical structure of the Flare data set, showing thousands of files and directories as nested rectangles whose areas encode file size and whose color encodes depth in the hierarchy. Hovering highlights the ancestors of the hovered node. The visualization uses D3 v4 APIs including `d3.treemap`, `d3.stratify`, and `d3.scaleMagma`, rendering to SVG. Text labels are clipped per rectangle, and node rects change stroke and dimensions on hover.

Treemap from bl.ocks.org

This treemap visualizes the hierarchical structure of the Flare data set, using nested rectangles whose areas encode each leaf’s size value. Users can toggle between summing by size or by count via radio buttons, which triggers a smooth 750ms transition of the rectangles. The visualization is built with D3 v4, using `d3.treemap` with the resquarify tiling function, `d3.hierarchy`, and `d3.scaleOrdinal` for color coding by parent category. The SVG rendering includes clip-paths for text labels and tooltip titles on each leaf.

Treemap from bl.ocks.org

This treemap shows the hierarchical structure of the Flare data set, with nested rectangles sized by either data value or leaf count. Rectangles are colored by parent category and labeled with truncated names. The visualization transitions between the two sizing modes over 750 milliseconds after a two-second delay, using the `d3.treemap` layout with a resquarify tiling function. The implementation uses D3.js v4 to render SVG elements, with text clipping via `clipPath` and an ordinal color scale based on `d3.schemeCategory20`.
