A hierarchical tree diagram visualizes global health data, organizing countries as parents, disease categories as their children, and individual diseases as leaves. The layout uses a vertical tree structure where nodes are color-coded by depth: orange for countries, blue for categories, and green for diseases. Custom data is rendered as an SVG using D3 v7, employing `d3.hierarchy` to structure the data and `d3.tree` with `d3.linkVertical` to compute and draw the paths. Node circles are styled with inline fills based on depth, with text labels positioned above each node.

This example presents a hierarchical tree diagram of global health data, organizing countries into disease categories and specific diseases beneath a “Global Health” root. The visualization uses an SVG-drawn tree layout, with colored nodes indicating depth: orange for countries, blue for disease categories, and green for individual diseases. The code builds the hierarchy with `d3.hierarchy()`, positions nodes using `d3.tree()`, and connects them with `d3.linkVertical()` paths. Labels appear above each circle, and the layout is calculated dynamically based on the 800×800 SVG dimensions.

Tree Graph

A hierarchical tree graph visualizes relationships among three countries, their health categories, and specific diseases. It uses a static, hand-coded dataset with India, France, and Brazil, each branching into two categories like Infectious or Respiratory, which further split into two diseases each. The code uses the d3.hierarchy and d3.tree layouts to compute node positions, and d3.linkVertical for curved link paths. Rendered as an SVG, circles and labels are color-coded by depth—orange for country, light blue for category, and light green for disease—with a legend clarifying the mappings.

Tree Graph ICE 8

A tree diagram shows the hierarchical structure of global health data, with countries (Brazil, India, Australia, Nigeria) branching into disease categories and specific diseases. The visualization uses a horizontal tree layout with colored nodes—orange for countries, light blue for disease categories, and green for diseases—to distinguish hierarchy levels. The code employs D3 v7's `d3.hierarchy` and `d3.tree` APIs to compute layout positions, and renders the SVG with `linkHorizontal` paths and circles via a `.join()` operation. A legend above the chart explains the color coding.

Tree graph

This example shows a hierarchical tree visualization of COVID-19 data, with a global root branching into continents, countries, and leaf nodes for cumulative confirmed cases, deaths, and recoveries. It uses the D3.js library, specifically the `d3.hierarchy` constructor and `d3.tree` layout, to compute node positions and render an SVG with styled circles and links. The data is embedded directly in the JavaScript, with each country node carrying a numeric value and color attributes that are not visualized further in the displayed output.

ICE 8 Tree

This horizontal tree diagram visualizes a hierarchy of global health data, tracing from a "Global Health" root through four countries (Canada, Japan, Germany, Kenya) into disease categories and specific illnesses. Node colors encode the tree depth, with a legend distinguishing global health, country, category, and disease levels. The code uses D3 v7’s `d3.hierarchy` and `d3.tree` layout, drawing links with `d3.linkHorizontal` and rendering nodes as SVG circles and text labels. Styling is minimal, relying on CSS classes for links and nodes.

Tree

This example shows a hierarchical tree of medical fields and related professionals, with nodes color-coded by generation depth. The visualization uses d3.stratify() to structure the flat parent-child data, d3.tree() to compute the layout, and SVG circles, paths, and text elements for rendering. Labels appear to the right of each node, and brown cubic Bézier curves connect parents to children. The background and text styling come from the linked stylesheet.

Tree graph

This tree visualization displays COVID-19 statistics by region, from the global root down to individual countries and their cumulative confirmed cases, deaths, and recoveries. The example uses D3 v7’s `d3.tree()` layout and `d3.hierarchy()` to position nodes in a hierarchical structure within an SVG. Leaf nodes carry named values such as “Cumulative Confirmed Cases - 150000,” while branch nodes group continents and countries. The code assigns data-driven properties like `type` and `level` to each node, though the visible rendering draws nodes as white circles with steelblue strokes and gray linking paths.

Tree graph

A tree graph visualizes a hierarchy of COVID-19 data, displaying cumulative confirmed cases, deceased, and recoveries for countries grouped by continent, with each leaf node labeling the specific metric and its value. The static SVG rendering relies on the d3.tree() and d3.hierarchy() APIs to compute the tree layout based on the provided data structure, using node circles, text labels, and connecting links styled via CSS.
