A collapsible tree diagram displays hierarchical data loaded from a remote JSON file, with nodes rendered as circles and labels connected by curved paths. Users can click any node to expand or collapse its subtree, triggering smooth 750ms transitions that reposition nodes and redraw links. The D3.js v6 code uses the `d3.tree` layout, `d3.hierarchy`, and custom diagonal path functions, with SVG elements animated via `transition()` and `attrTween`-style updates. Nodes initially collapse after the second level, showing partially expanded structure.

ICE-8(11630234)

This interactive D3.js tree diagram displays a manually defined family hierarchy, with clickable nodes that collapse or expand their child branches. The visualization uses `d3.layout.tree` to compute node positions and `d3.svg.diagonal` for the connecting links, with smooth transitions between layout states. Node circles are colored red by default or lightsteelblue when collapsed, and text labels show names. The SVG rendering includes animated enter, update, and exit transitions driven by click events that toggle a node’s `children` and `_children` properties. The code loads D3 v3.5.17 from a CDN.

ICE 8 Family Tree Simple

This interactive family tree visualization displays hierarchical relationships using a node-link diagram with expandable and collapsible branches. The D3.js v3 layout algorithm arranges nodes vertically by depth, with color-coded node types and labeled links showing connection directions. Users can click nodes to toggle child visibility, with smooth 750ms animated transitions. The visualization supports pan and zoom through D3's zoom behavior, while tooltips provide additional node information. The tree structure comes from a JSON data file loaded via d3.json, with SVG rendering for all graphical elements including custom arrow markers and drop shadows.

A collapsible tree diagram visualizes hierarchical family relationships, rendering nodes and links as an animated SVG. The example uses D3.js version 3.5 with the `d3.layout.tree` and `d3.svg.diagonal` APIs to compute the layout and draw curved paths. Circles and text labels represent individuals, and clicking a node toggles its children’s visibility with smooth transitions. Styling is applied via external CSS, and the input data comes from a local `qn_tree.json` file.

ICE8: Tree Diag

This interactive tree diagram visualizes a hierarchical family structure, with each node representing a person and links showing parent-child relationships. The visualization uses D3.js (v3) with a tree layout and SVG rendering to display the structure. Nodes are color-coded by depth level, with circles featuring distinct fills and strokes based on the JSON data's properties. Users can click any node to collapse or expand its children, triggering smooth animated transitions that reposition the nodes and links using D3's diagonal path generator.

ICE 8: Tree and Network

This example visualizes a hierarchical tree as a network of nodes and links, using circles for nodes and red paths for edges. The tree structure is derived from a small inline dataset with parent-child relationships. The visualization uses D3.js v6 to stratify and compute the tree layout, and renders SVG elements with animated transitions. Additionally, circles appear with a transition effect, and text labels fade in based on their depth in the tree, demonstrating the use of D3's transition API.

ice8 -Tree

This interactive tree diagram visualizes a hierarchical dataset, with nodes representing names and animated connections showing parent-child relationships. Clicking a node toggles the expansion or collapse of its children, smoothly transitioning the layout. Built with d3.layout.tree, it uses d3.svg.diagonal for curved links and d3.json to load the external qn_tree.json file. The SVG rendering includes a fixed-depth normalization, orange node strokes, and semi-transparent links, with all nodes positioned based on their depth in the hierarchy.

This interactive tree diagram visualizes a botanical classification hierarchy, from Plants down to Monocots and Dicots. The SVG visualization uses D3.js v3’s `d3.layout.tree` and `d3.svg.diagonal` to render nodes and curved links. Clicking a node toggles its children via a transition, animating the tree’s layout. Circles are colored and stroked based on the `level` and `type` fields in the data, with labels positioned around each node.

ICE8 - Interactive Tree Graph

This example presents an interactive family tree visualization using D3.js version 3.5.17. The tree layout (`d3.layout.tree`) arranges hierarchical data with named family members, while SVG circles and text labels render each node and curved diagonal paths (`d3.svg.diagonal`) connect parent-child relationships. Clicking any node toggles its children, triggering smooth 750ms transitions that animate nodes and links to new positions. The code uses fixed-depth spacing (180 pixels per level) and custom styling with teal nodes and thick teal links against a white background.
