This tree chart visualizes a hierarchical dataset of continents, countries, cities, and landmarks, using color-coded nodes to distinguish each level. The SVG visualization is built with D3.js version 3.5.17, employing the `d3.layout.tree` for node positioning and `d3.svg.diagonal` for curved connecting links. The interactive animation reveals the structure progressively, with each parent node expanding to display its children over a one-second duration. Data is hardcoded in the `plantGenerationsData` array, and the rendering uses a white node fill with steelblue strokes against gray links.

Tree Chart

An animated hierarchical tree chart displays a dataset of continents, countries, cities, and local landmarks, with nodes color-coded by level: black for roots, blue for countries, red for cities, and green for landmarks. The visualization uses D3.js version 3 layout and diagonal SVG paths, with an in-memory JSON array as the data source. Transitions animate the tree’s expansion, while styling from CSS handles node circles and text.

Tree Chart

This hierarchical tree chart displays geographic relationships, branching from continents to countries, cities, and landmarks. The data is hardcoded in JavaScript as nested JSON objects. The visualization uses D3.js version 3.5.17, specifically the `d3.layout.tree` and `d3.svg.diagonal` APIs to position nodes and draw curved links. Each node is color-coded by hierarchy level: black for continents, blue for countries, red for cities, and green for landmarks. The animation and SVG-based rendering apply a 1000-millisecond transition duration when updating the tree structure.

Countries tree

This interactive tree diagram visualizes the hierarchical relationship between continents, countries, and major cities, using color-coded nodes for each type (e.g., purple for root, green for continents). Rendered as an animated SVG, users can click nodes to expand or collapse branches. The implementation leverages the D3.js `d3.layout.tree` API to compute the layout, with custom CSS classes for node styling and tooltips. The data structure is loaded from an external `Tree.json` file, and the interaction supports zooming and dragging through D3's `d3.behavior.zoom`.

Countries Tree

This example visualizes a hierarchical dataset of countries organized by continent and subregion as a dendrogram. The tree layout positions all nodes in a horizontal cluster, with country names displayed at varying font sizes based on depth using the d3.cluster and d3.hierarchy APIs. Curved link paths are generated with d3.linkHorizontal, while d3.zoom enables panning and scaling of the SVG canvas. The data is loaded from a JSON file and rendered entirely in SVG with custom styling.

Tree Diagram

This interactive tree diagram displays a hierarchical dataset of world geography, starting from the root "World" and branching into continents, regions, and countries. It is rendered using D3 v5 with an SVG output, employing the `tree` layout and `hierarchy` functions. The visualization uses `linkHorizontal` to draw curved links between nodes and supports zooming and panning via the `zoom` behavior. Text labels are positioned based on node coordinates, with font sizes scaling by depth, and the data is loaded from a JSON file.

Tree!

This visualization shows a hierarchical tree of world geography, starting from continents and drilling down to countries and subregions. The data is structured as nested JSON objects representing the world, with nodes labeled for regions like Asia and individual nations. Built with D3 v5, it uses the `tree` and `hierarchy` layout functions to compute node positions and `linkHorizontal` to draw the connecting paths. Text labels scale in font size based on depth, and the entire SVG canvas supports pan and zoom via the `zoom` event.

TREE

This tree visualization displays a hierarchical dataset of world countries organized by continent and subregion, using a horizontal icicle-style layout. The D3 v5 code builds the structure with `tree()` and `hierarchy()`, renders edges as SVG paths via `linkHorizontal()`, and labels nodes with scaled text. Users can zoom and pan through the SVG canvas using the `zoom()` interaction API, with the viewport transform applied to a group element. Data comes from a JSON file, and styling uses the Maven Pro font with cyan edges.

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.
