This example displays a treemap visualization of hierarchical data using D3 v5’s `d3.hierarchy` and `d3.treemap` layouts. The SVG renders nested rectangles sized proportionally to node values, with labels for named leaves and empty labels for internal branches. The code manually constructs the dataset in `index.js`, sums values via `root.sum`, and applies layout properties like `paddingOuter`. Rectangles and text are appended into grouped `<g>` elements, with styling from `styles.css` using royal blue fills and white strokes.

TreeMap Layout

This example demonstrates a treemap layout using D3 v5, displaying hierarchical data as nested rectangles sized proportionally to their values. The visualization shows four labeled nodes—three leaf nodes (C1, C2, C3) with varying values beneath a parent node (B1), alongside a sibling node (B2)—all enclosed within root A1, with padding and gaps between groups. It uses `d3.hierarchy` to structure the data and `d3.treemap` to compute the layout, rendering rectangles and text as SVG elements. The treemap applies an outer padding of 16 pixels and scales to a 400×200 pixel area, with a static dataset defined in the code.

Treemap layout (with labels)

A treemap layout visualizes a small hierarchical dataset, with nested rectangles representing the root node A1, its children B1 and B2, and the grandchildren C1, C2, and C3. Each rectangle is colored cadetblue, and labels show the node names. The example uses the `d3.treemap` layout with `d3.hierarchy` and `rootNode.sum` to compute sizes, then renders the result as SVG rectangles and text elements via data joins on `g` nodes.

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.

Fork of Untitled

A zoomable treemap visualizes hierarchical data, with rectangles sized by a user-selected measure and color-coded by an optional metric. The chart supports interactive drilling down through levels, showing breadcrumb navigation and tooltips on hover. Built with D3 v4, the visualization uses `d3.treemap` for layout, `d3.hierarchy` and `d3.nest` for data structuring, and SVG with animated transitions for smooth zooming between levels. Hover effects highlight parent-child relationships, and the code includes customizable parameters for multiple measures and tooltip fields.

Fork of D3 Starter

This example demonstrates a treemap visualization that recursively partitions a rectangular canvas into nested rectangles, with each leaf node sized proportionally to its value. The code builds the layout manually using D3’s `scaleLinear` for area allocation and `scaleOrdinal` with the `schemeCategory10` color palette. It also computes text dimensions with a custom `visualWidth` helper and uses CSS-based font-family detection for cross-system compatibility. The data is loaded from a local JSON file and rendered as SVG rectangles and text labels.

Fork of Treemap

This visualization shows a hierarchical treemap where rectangular tiles represent data categories, with size indicating their relative production values. The treemap displays five groups (grp1–grp7) nested under an origin node, each filled with a uniform teal color and labeled with white text. Built with D3 v6, the code uses `d3.stratify` to convert CSV data into a hierarchy, `d3.treemap` to compute tile positions, and SVG `rect` and `text` elements for rendering.

Layout Test

This example demonstrates a hierarchical tree layout rendered as an SVG visualization, with data representing a page structure of components and partials. The tree uses d3.tree and d3.hierarchy to compute node positions, while d3.linkHorizontal draws curved paths between parent and child nodes. The visualization supports pan and zoom through d3.zoom, with the zoom transform applied to a group element containing the rendered tree. A data store module supplies the hierarchical data, and the code includes a typo where circles are appended using the incorrect tag name instead of “circle.”

HW2 Treemap

This example shows a hierarchical treemap visualization where nested rectangles represent data values, with each rectangle’s area proportional to its value and text labels displaying the numeric data. The layout is generated using D3 v5’s `treemap` and `hierarchy` functions, which compute rectangle positions and sizes from a nested data structure. The SVG rendering applies a semi-transparent royal blue fill with white strokes to the rectangles, while white Helvetica text labels each node. The treemap layout is configured with a 900 by 400 pixel size and a 16-pixel outer padding, and the root’s values are summed using the `sum` method.
