Forked from Example

This example shows a hierarchical data visualization of hip replacement experts, organized as a tree with root "Hip Replacement" branching into countries, cities, institutions, and expert names. The data is loaded asynchronously from a CSV file using D3's `d3.csv` function. The visualization updates in response to the dataset, with the tree layout computed using `d3.tree()` and node positions linked via `d3.linkHorizontal()`. SVG rendering and animation are implemented with D3 v7, with a dark blue background applied to the page.

Fork of Example

This example shows a hierarchical tree visualization of hip replacement experts, organized by country, city, and institution, based on data loaded from a remote CSV file. The tree uses a collapsible layout where nodes represent each level of the hierarchy, with the root labeled "Hip Replacement" and branches extending to countries, cities, institutes, and individual experts. Built with D3 v7, it uses `d3.csv` for data loading, `d3.hierarchy` and `d3.tree` for layout, and `d3.linkHorizontal` for rendering the curved links in SVG. The code processes the data by filtering unique values for each category and sorting by rankings before constructing the nested tree structure. The visualization is animated, with a dark blue background styling applied to the page body.

Fork of Example

A collapsible D3 tree diagram visualizes the hierarchical relationships within a dataset on hip replacement rankings, organized by country, city, institution, and expert. The visualization uses a tidy tree layout calculated with `d3.tree()` and rendered with SVG paths. Data is loaded asynchronously from a CSV file via `d3.csv`, then processed into a nested tree structure. The hierarchy is built with `d3.hierarchy()`, and nodes use `d3.linkHorizontal()` for curved connecting links, with animations for collapsing and expanding branches.

Example

This example shows an animated D3 tidy tree visualization of hip replacement experts, organized hierarchically by country, city, institution, and expert name. The code loads CSV data from a gist URL and uses `d3.csv`, `d3.hierarchy`, and `d3.tree()` with `d3.linkHorizontal` to render the collapsible tree structure as an SVG. Nodes are initially collapsed based on name length, and the layout adapts to the window size using `window.innerWidth`.

Fork of C4SAM Services

This interactive D3 tree diagram visualizes a hierarchical dataset of hip replacement services, organizing experts by institution, city, and country. The visualization fetches CSV data from a GitHub gist and uses `d3.csv` to load it, then constructs a nested tree structure through successive filtering and sorting operations. The rendering uses `d3.hierarchy` and `d3.linkHorizontal` to draw the branching layout, with SVG output that responds to the window size. The animation is triggered by node interactions, though the specific transitions are not detailed in the visible code.

Fork of C4SAM Services

This visualization shows a hierarchical tree of hip replacement services, branching from countries to cities, institutions, and experts, with each level sorted by its ranking metric. The code uses D3.js v7 to build and render the tree structure from CSV data fetched via `d3.csv`, applying `d3.hierarchy` and `d3.tree` layouts. It renders as an SVG with an animated collapse-and-expand behavior for nodes, where deeper levels are initially collapsed until clicked. The dark blue background (`#000033`) and horizontal link paths (`d3.linkHorizontal`) create a readable flow across the full window width.

Fork of Tree Example

This interactive tree diagram visualizes a hierarchical dataset using D3.js, with nodes representing categories and leaves sized by population data from a CSV file. The visualization shows a branching structure where users can click nodes to expand or collapse children, with animated transitions between states. Built with D3's layout tree and diagonal APIs, it renders as an SVG with smooth 750ms transitions, while node circles display tooltip information on hover.

Fork of Fork for plotting tree

This example displays a hierarchical tree visualization of hospital emergency room data, organized by department referral and showing individual patient details. Using D3.js v7, it fetches CSV data from a GitHub repository, transforms the flat records into a nested structure, and renders the result as an SVG tree layout. The visualization employs `d3.csv`, `d3.hierarchy`, and `d3.tree` to position nodes, with `d3.linkHorizontal` generating curved links between parent and child elements. Each patient node branches into leaf nodes for attributes like gender, age, date, and wait time.

Fork of Tree

This example visualizes a hierarchical dataset as a tree diagram, with nodes represented as red-stroked circles and connecting links drawn as paths. The tree layout is computed using `d3.stratify` and `d3.tree`, and the SVG rendering animates the paths and circles on load. Node labels fade in with delays based on depth, using D3 transitions. The data is hardcoded as an array of parent-child pairs, and the visualization is built with D3 v6 in a plain HTML page.
