This example shows a collapsible tree diagram with a horizontal orientation, displaying hierarchical data with parent and child nodes connected by curved links. The tree layout is computed using `d3.layout.tree`, and links are drawn as SVG paths using `d3.svg.diagonal` with a custom projection that swaps x and y coordinates to achieve the horizontal layout. Nodes are rendered as circles with text labels, and the code uses D3 version 3.5.17, loading the library from a CDN. The data is hardcoded as a JavaScript array with nested objects representing the tree structure.

AI-generated description

Test code for a tree diagram with the diagonal variable edited to allow for placement of the relative positions of the links to be altered. However the direction that the links head is vertically, but the orientation of the tree is desired to be horizontally.

Collapsible Tree Example

This example shows a static tree diagram generated from flat, parent-child data, with nodes and links rendered as SVG circles and paths. The code converts the flat data into a hierarchical tree structure using `d3.layout.tree` and draws it with `d3.svg.diagonal` for the curved links. It relies on the D3.js library (version 3.5.17) and uses standard SVG elements like `circle`, `text`, and `path` for visualization. The diagram is fixed-depth, with no interactive collapse or update behavior.

Collapsible Tree Example

This example shows a vertical d3.js tree diagram with a fixed set of hierarchical data, including a top-level node with two second-level branches and further descendants. While titled "collapsible," the provided code is a simplified version that renders the tree without any interactive update or collapse functionality. The visualization uses the D3 v3 `d3.layout.tree` for layout and `d3.svg.diagonal` for link paths, with nodes drawn as white circles and labels positioned above or below each node. All elements are rendered in SVG, and the data is hardcoded in the script.

Collapsible Tree Example

This example shows a static tree diagram visualizing hierarchical data, with nodes and links styled using dynamic colors based on the data attributes. The visualization encodes numeric values as the radius of each node’s circle and uses distinct colors for node fill, stroke, and links. The code uses the D3.js layout in `d3.layout.tree` and the `d3.svg.diagonal` API to draw curved links. It loads data from an embedded JavaScript array and renders the graphic as an SVG, with the tree laid out horizontally from left to right.

Collapsible Tree Example

A collapsible tree diagram displays hierarchical data as a set of linked nodes, where each node’s children can be expanded or hidden by clicking, though the example code does not yet implement click interactions. The flat CSV data, containing parent-child relationships, is converted into a tree structure using a name-to-node map. The visualization is rendered as an SVG using D3.js version 3.5, with `d3.layout.tree` computing the layout, `d3.svg.diagonal` drawing curved links, and nodes represented by circles and text labels.

Collapsible Tree Example

This example shows a static hierarchical tree diagram with nodes and links loaded from an external JSON file. The visualization uses the D3.js v3 library, specifically the `d3.layout.tree` for computing node positions and `d3.svg.diagonal` for drawing curved connecting paths between parent and child nodes. Nodes are rendered as SVG circles with text labels, and the layout is normalized to a fixed depth of 180 pixels per level. The data source is a JSON array containing a top-level node with two children, one of which has its own descendants, demonstrating basic tree structure rendering without interactivity.

Collapsible Tree Example

This example shows a collapsible tree diagram where nodes are displayed as SVG images and connected by curved links, with node labels and link strokes colored by data attributes. The visualization presents hierarchical data from a static JavaScript array, using D3 v3’s `d3.layout.tree` to compute the layout and `d3.svg.diagonal` to draw the links. Node icons are loaded from external SVG files (`rect.svg`, `rect2.svg`) via `xlink:href`, and link colors reflect each target’s `level` property. The code defines nodes with `image` elements and text labels, while the tree structure and styles are set in the HTML and CSS.

Collapsible Tree Example

This example shows a collapsible tree diagram where each node displays an image and a text label. The visualization uses a static, hard-coded dataset embedded in the code, with nodes positioned by depth and connected by curved links. Built with D3.js version 3, it employs `d3.layout.tree` for the layout, `d3.svg.diagonal` for the paths, and SVG elements for rendering. Node images are loaded from local files, while link strokes are colored dynamically based on the target node’s “level” property.

Collapsible Tree Example

This example shows a static tree diagram with a root node branching into two levels of child nodes, using text labels and circular markers connected by curved links. The visualization renders in SVG via D3.js version 3.5, using the `d3.layout.tree` for hierarchical positioning and `d3.svg.diagonal` for link paths. The code defines a fixed dataset inline and normalizes node depth for horizontal spacing, though it lacks the interactive collapse-and-expand behavior of the original Bostock example it derives from.
