Forked from Collapsible Tree Hierarchy - Real Data - Structured

This interactive tree visualization displays the hierarchical structure of MeSH (Medical Subject Headings) data, with nodes representing terms and branches showing parent-child relationships. Users can click nodes to collapse or expand subtrees and navigate through the hierarchy. Built with React and d3.v6, the visualization uses SVG rendering with smooth 250ms transitions, `root.descendants()`, and `tree(root)` for layout computation. Node circles scale based on child count, and click events trigger nested navigation through a node stack while a tooltip shows the selected term's name and key.

Collapsible Tree Hierarchy - Real Data

This interactive collapsible tree visualizes a hierarchical structure of medical terms derived from MeSH data. The visualization displays the tree as an SVG graphic, with nodes representing medical concepts and connections illustrating their relationships. Users can click on nodes to expand or collapse subtrees, while a dedicated info panel shows the term’s name, key, and description. Built with D3.js v6, the tree uses animated transitions via `transition()` and `attrTween` to smoothly reposition nodes and links. The code implements a custom `convertToHierarchy` function to transform flat JSON data into a nested tree structure.

SAVE OF Collapsible Tree Hierarchy - Real Data

This visualization presents a collapsible tree hierarchy of MeSH (Medical Subject Headings) data, organized into a hierarchical structure based on the "MN" field and labeled with descriptive names. Users can click nodes to expand or collapse branches and navigate the hierarchy. Built with React and D3.js v6, the visualization uses SVG and animations to render nodes with dynamic radii and text labels. The data is loaded from a remote JSON file, and custom JavaScript functions categorize entries by their descriptions to sort the tree’s root children.

Collapsible Tree Hierarchy - Real Data

A collapsible tree hierarchy displays real hierarchical data, with nodes that expand and collapse on click. It also enables navigation by re-rooting the tree view to the clicked node, while a stack tracks the path back to previous roots. The visualization uses d3.v6’s tree layout and transitions, rendering SVG circles and text labels with animated updates. A node-info div shows details for the selected item, and the canvas height dynamically adjusts to fit the visible hierarchy.

Collapsible Tree Hierarchy Reformatted - Real Data

This interactive collapsible tree visualization displays hierarchical data as an SVG with animated transitions between expanded and collapsed states. Users click nodes to re-root the tree and reveal child nodes, while a dynamic info panel shows the selected node’s ID and name. Built with d3.v6 and React, it uses the `transition()` API for smooth resizing and layout updates, with node positions computed via `root.descendants()` and `root.links()`. The rendering relies on SVG elements, including circles and text, styled with CSS. The dataset originates from a real source, as indicated in the example’s metadata.

Collapsible Tree Hierarchy - Real Data - Structured

This example presents a collapsible tree hierarchy using real data, rendered as an SVG. The visualization displays nodes that can be clicked to expand or collapse their children, revealing the structured relationships in the data. Built with React and D3 v6, it uses `d3.hierarchy` to process the data and `d3.tree` for layout, with custom JavaScript handling node clicks and updating the tree structure dynamically through `updateTree`.

Collapsible Tree

This interactive visualization displays a hierarchical tree structure, allowing users to click on nodes to expand or collapse their child branches. The tree’s layout dynamically repositions nodes with animated transitions, adjusting the SVG canvas height to fit the visible structure. Built with React and D3 v6, it uses the `d3.tree()` layout, `d3.linkHorizontal()` for connecting links, and reads hierarchical JSON data from a remote file. Node labels are rendered alongside circular markers, with parent and leaf nodes shown in different colors.

This example shows an interactive collapsible tree hierarchy, allowing users to click on nodes to expand or collapse their children, and to navigate the tree by re-rooting it at a clicked node. The visualization uses D3.js v6 to compute a tidy tree layout with `d3.hierarchy` and renders it as an SVG, with animated transitions for all changes. A custom node-info div displays the name and ID of the last clicked node. The code also manages a stack to remember previous roots, enabling backward navigation through the hierarchy.

Fork of SAVE SPOT Medical Data Tree - Category (retry)

This interactive tree visualization explores the Medical Subject Headings (MeSH) hierarchy, using a force-directed layout to display the relationships between medical categories and their sub-terms. Built with D3.js v6 and React, the tree is rendered as SVG elements, with animated transitions when nodes are clicked to expand or collapse child categories. The code processes flat MeSH data into a hierarchical structure, categorizing entries based on regex patterns matching their descriptions. Users can navigate through the tree by clicking nodes, which triggers smooth animations and displays node-specific information in a floating div.
