This tree map visualizes hierarchical sales data for US states and cities using a treemap layout. The visualization encodes each leaf node as a rectangle, with area proportional to sales values and color assigned by parent state via an ordinal scale with the Tableau 10 scheme. The code loads data from a JSON file using `d3.json`, builds a hierarchy with `d3.hierarchy` and `sum`, then applies `d3.treemap` to compute positions. Rectangles and white labels are rendered as SVG elements within a container group.

Interactive Visualisation

A treemap visualizes hierarchical sales data from a UK sales CSV, with regions and towns nested by country. Users hover over rectangles to see a breadcrumb showing the region, town, and total sales value. Built with React and D3 v7, the chart uses `d3.stratify`, `d3.treemap`, and `d3.scaleOrdinal` to structure and color the hierarchy, while SVG rendering and `mouseenter` events drive the interactive labels and layout.

Tree Map for countries and states

This example presents a tree diagram mapping countries to their respective states, using a hierarchical dataset structured with parent-child relationships. The visualization uses D3 v5’s `d3.stratify` to convert the flat data into a hierarchy, then applies `d3.tree()` to compute the layout. Nodes are rendered as circles colored by depth (purple, dark red, and magenta), connected by red cubic Bézier curves, with labels placed next to each node. The implementation is based on code adapted from a Crypters Infotech tutorial.

usa Tree

This visualization shows a hierarchical tree of U.S. states and cities, with the USA at the root, three states (Florida, Texas, Virginia) as children, and their major cities as leaves. The code uses `d3.stratify()` to convert flat parent-child data into a hierarchy and `d3.tree()` to compute node positions. Circles represent each node, colored by depth via a `setGeneration` function, with animated SVG path links that transition from source to target positions and text labels displayed in yellow.

United States, States Tree

This example visualizes a hierarchical tree of U.S. states, counties, and cities, with nodes colored by depth (orange, blue, pink, red, or yellow). Using D3.js v6 and the `d3.stratify` and `d3.tree` APIs, it positions nodes and animates path connections between parent and child elements. Rendered as an SVG with transitions, the code draws circles and text labels for each node, with hardcoded data showing relationships like Texas to Denton to Lewisville.

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 example visualizes a hierarchical dataset as a treemap, using rectangles sized by each node’s `degree` value and colored by its `domain` attribute to reveal the relative prominence of categories. Built with D3 v3, the code loads hierarchical JSON data and applies the `d3.layout.treemap` layout with custom padding. Node labels and background colors are assigned via D3 selections, with positions and dimensions computed by the layout and applied through inline styling. The visualization provides a compact overview of the dataset’s nested structure and degree distribution.

Treemap Demo

This treemap demo shows a hierarchical dataset of a CEO’s employees, grouped into three boss-level parents, with each leaf rectangle sized by its numeric value. The interface includes buttons to mutate the data: changing leaf values, adding or removing child nodes, and adding or removing entire parent groups. The visualization updates with animated transitions on rectangles and text labels, rendered in SVG via React. It uses d3.hierarchy and d3.treemap for layout, d3.scaleOrdinal for color coding by parent, and d3.scaleLinear for opacity based on value.

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.
