A treemap organizes the public API of the D3.js library, grouping functions by category such as Selections, Scales, SVG, and Arrays. Each rectangle’s size reflects the number of functions in that section, while its fill color encodes the category. The visualization uses the `d3.layout.treemap` algorithm to position the cells and `d3.nest` to count functions per type from an `api.json` file. Color assignments come from `d3.scale.category20c`, and the SVG elements are constructed with `d3.select` and `d3.append`.

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.

visualization9d3

A D3.js treemap displays hierarchical data as nested rectangular nodes, sized proportionally to each value. The visualization shows five course categories with descending values, using a spectral color scale for differentiation. The code embeds a static dataset directly and builds the hierarchy using `d3.hierarchy` with a sum accessor, then applies `d3.treemap` to compute the layout. Each leaf node renders as a positioned `div` element, with dimensions derived from the treemap’s computed coordinates and colors assigned via `d3.interpolateSpectral`.

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.

d3 template

This example renders a treemap visualization using D3.js v6 in a React environment. It displays hierarchical data as nested rectangles, with each leaf node's area representing its value and labeled with its name. The code loads JSON data from a remote GitHub source, converts it into a hierarchy using `d3.hierarchy`, then computes the spatial layout with `d3.treemap`. The resulting SVG rectangles and text labels are appended to the chart, with leaves filled in slate blue, providing a clear visual breakdown of the data's composition.

Treemap from bl.ocks.org

A treemap visualization displays the hierarchical structure of the flare.json dataset, with nested rectangles sized by either node size or leaf count. The interactive chart allows toggling between these two aggregation modes via radio buttons, triggering a smooth animated transition. Built with D3 v4, the visualization uses `d3.treemap`, `d3.hierarchy`, and `d3.scaleOrdinal` for coloring, rendering SVG cells with clipped text labels and tooltips.

Treemap from bl.ocks.org

This treemap visualizes hierarchical data, such as the flare.json dataset, using nested rectangles to represent size values, with an option to re-sort by count. It shows an interactive animation that smoothly transitions between these two aggregation modes. Built with D3.js v4, the code uses `d3.treemap`, `d3.treemapResquarify`, and `d3.hierarchy` to process data, while SVG rendering and `d3.transition()` handle the animated updates. The example also includes a color scale from `d3.schemeCategory20` for visual distinction.

Untitled

This example displays a treemap visualization of hierarchical data, with the current view showing video game sales grouped by platform, or movie and Kickstarter data sets selectable via links at the top. It uses the d3 v4 API, specifically `d3.treemap()`, `d3.hierarchy()`, and `d3.scaleOrdinal` with the `schemeCategory20` color palette, to render the nested rectangles. The SVG output includes tooltips on mouseover, which display the name, category, and value of each tile using data attributes.

D3 Source Treemap

This treemap visualizes the file size, in bytes, of the D3.js 4.4.0 source code, broken down by module and individual source file. Built with D3 v4, it renders as an SVG using `d3.treemap` and `d3.stratify` to create the hierarchy from a CSV containing file paths and sizes. Each leaf cell is a clickable link to the corresponding source file on GitHub, with its color assigned via `d3.scaleOrdinal` and `d3.schemeCategory20`.
