This interactive tree diagram visualizes a hierarchical dataset showing a root node branching into map types, including world map, continents, and country maps with specific countries like India, Japan, and China. Users can click on nodes to expand or collapse subtrees, with smooth animated transitions between states. The visualization uses D3.js version 3.5.17, specifically the `d3.layout.tree` algorithm and `d3.svg.diagonal` for curved link paths, rendered as SVG with CSS styling. Data is loaded asynchronously from a JSON file, and node positions are normalized at fixed depth intervals of 180 pixels.

Assignment2_Task7_Tree

This animated tree diagram shows hierarchical geographic data, with continents branching into countries and cities. The visualization expands nodes progressively using D3’s `d3.layout.tree` and `d3.svg.diagonal` APIs, with each node’s position calculated by depth. Node colors derive from the dataset’s `fill` properties, while SVG circles and text labels update dynamically through node enter/update transitions. The code uses D3 version 3.5.17 to render the structure, with fixed-depth spacing and a 500-pixel-tall frame.

Assignment 2 Question 7_Tree Chart

This interactive tree chart displays hierarchical geographic data, showing continents branching into countries, then cities, and finally landmarks. The visualization uses D3.js version 3’s `d3.layout.tree` to compute the node positions and `d3.svg.diagonal` to draw the curved connecting links between parent and child nodes. Each node is rendered as an SVG circle with color-coded fills based on its hierarchy level, while text labels identify each entity. The animation feature uses D3 transitions with a 1000ms duration to smoothly update the tree layout, and the data is passed directly from a local JavaScript array.

Assignment 2 Q7-1 Tree

This interactive tree visualization displays a hierarchical dataset of devices, branching from "Devices" into Laptops and Mobiles, and further into specific models. The D3.js (v3) layout places nodes as colored rectangles with labels, using smooth animations for expansion and collapse. It renders SVG graphics with custom CSS for node states and tooltips, while the JSON data source drives the structure. The implementation leverages `d3.layout.tree` for positioning and `d3.behavior.zoom` for pan and zoom interactions.

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.

Tree Example with worlds and their countries

This interactive tree diagram displays a hierarchical view of the world’s continents and selected countries, with nodes that expand and collapse on click. Built with React and D3.js (v3), it uses `d3.layout.tree` for positioning and `d3.svg.diagonal` for curved links, all rendered as animated SVG transitions. The visualization starts with a root node for “world” and branches into continents like Asia, Europe, and Africa, with Asia further detailed into subregions and specific countries such as India, Austria, and Belgium. Node colors and stroke styles are defined via CSS classes.

Assignment2_Task7_Part1

An interactive collapsible tree diagram visualizes a hierarchical dataset of fruits and their varieties from a JSON file. Node types receive distinct colors, and rectangular boxes represent each item. The visualization uses D3.js v3 for layout and rendering, with SVG elements for nodes and links. It supports zooming and panning via `d3.behavior.zoom`, and includes CSS-defined tooltips and drop shadows for enhanced interactivity.

Assignment6_Question7_Tree

This interactive tree diagram displays the hierarchical relationships among programming languages and their associated frameworks, with data loaded from a JSON file. Users can click nodes to expand or collapse branches, triggering smooth animations. The visualization uses D3.js v3 layout and rendering APIs, including `d3.layout.tree`, SVG elements, and zoom behavior for panning. Node colors differentiate hierarchy types, while tooltips and directed links enhance readability. The implementation combines React for the application structure with D3 for data binding and SVG animation.

Fork of Fork of Fork of Tree 7

This interactive tree diagram visualizes the hierarchical relationships in a small JSON dataset (qn_tree.json), starting from a root node and branching through named individuals like Ganne, sai, and bindu. Nodes expand and collapse on click, with smooth animated transitions of curved links and repositioned labels. The implementation uses D3 v3’s `d3.layout.tree`, `d3.svg.diagonal`, and standard SVG transitions to update positions over a duration of 1100 milliseconds, while circles and text change styling based on collapsed state.
