Treemap Padding

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`.

Stretched Treemap

This example uses a stretched treemap to visualize the hierarchical structure of the Flare dataset. The rectangles have a fixed aspect ratio of 4:1, which is achieved by first computing a squarified layout with a target ratio of one and then stretching the result horizontally. The treemap is built with `d3.treemap` and `d3.treemapSquarify.ratio`, while color and labels are assigned to each node via `d3.scaleOrdinal` and HTML `div` elements. Data is loaded from a CSV file with `d3.csv`.

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.

Treemap by Count

This treemap displays the hierarchical structure of the Flare dataset, counting each leaf node as equal in size rather than scaling by a numeric value. The visualization uses d3.stratify to build the hierarchy and d3.treemap with a custom sum function that assigns a value of one to non-zero leaves. Each rectangular leaf is rendered as an HTML div, colored by its top-level category using d3.scaleOrdinal with schemeCategory10, and labeled with the node name split across multiple lines.

Treemap

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.

Treemap Example

This treemap visualizes the hierarchical flare dataset, showing relative leaf-node values as nested rectangles colored by their top-level parent category. Built with D3 v6 and rendered as SVG, the example implements a custom treemap layout algorithm via recursive space partitioning that alternates between horizontal and vertical splits. The code uses d3.scaleLinear for proportional sizing, d3.scaleOrdinal with d3.schemeCategory10 for colors, and calculates text visibility based on rectangle dimensions. Data is loaded from a JSON file and displayed with interactive hover effects absent, focusing purely on static hierarchical encoding.

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.
