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 in d3

This example demonstrates a treemap visualization of hierarchical data, with nested rectangles representing the A1, B1/B2, and C1/C2/C3 nodes. It uses d3.treemap to compute the layout based on summed values, with padding and a fixed size of 800 by 400 pixels. The d3.hierarchy API organizes the data structure, while descendants are rendered as SVG groups, rects, and text elements using d3.select and join. The visualization clearly shows proportional area encoding, with rectangles colored in semitransparent cadetblue and labeled for each node.

Fork of TreeMap Layout

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 (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.

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.

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

This treemap visualizes hierarchical data by displaying nested rectangles whose sizes correspond to data values, with color encoding categories and group labels. The example demonstrates the d3.treemap layout with SVG rendering, applying a color scale via d3.scaleOrdinal and interactive tooltips on mouse events. It loads external JSON datasets from URLs, using D3's d3.json to fetch data. The visualization highlights the D3 v4 API for hierarchical layouts and data-driven styling, with the option to switch between video game, movie, and Kickstarter datasets.

TreeMap

This tree map visualizes a hierarchical log of user interface events from a browsing session, shown as nested rectangles whose sizes correspond to a time metric. The layout is computed with `d3.treemap()` on the loaded JSON data, with elements rendered as SVG `<rect>` and `<text>` nodes. The d3 hierarchy is processed through `d3.hierarchy()` and laid out with `d3.treemap()`.

Tree Map

This tree map displays hierarchical data as nested rectangles sized proportionally to their values. The example renders an SVG graphic at 960 by 500 pixels, pulling in D3 v5 from a CDN. The code imports `select` and `arc` from the D3 library, though the visualization logic itself remains minimal in the shown files. The page references a separate stylesheet and JavaScript bundle, with the SVG container set up for the treemap layout. The map is generated using D3’s standard tree-map approach, though the actual data and layout calculations are not explicitly defined in the visible code.
