This example shows a hierarchical fault tree for a Mars rover mission, displaying components and their potential failure modes. Operations branch into launch and transit phases, with nested nodes for subsystems like avionics, cameras, and the single-board computer. Each leaf node is labeled with a failure code such as D1, D2, or E1. The visualization uses D3 v4’s `d3.tree` and `d3.stratify` to convert a flat CSV file with dot-separated paths into a structured hierarchy, rendered as an SVG with curved links and styled node circles.

This example visualizes a hierarchical fault tree for a Mars rover mission, showing components like avionics, cameras, and batteries with their potential failure modes. The radial tree layout, rendered as an SVG using D3 v4, positions failure categories and specific faults around a circular structure. Data comes from a CSV file with hierarchical IDs, processed through `d3.stratify` and `d3.tree` to create the node hierarchy. Curved links connect parent-child nodes, with text labels rotated along the circumference to display component names and failure codes.

A radial tree visualization displays hierarchical operations data, with each node representing a mission phase or component. The layout arranges nodes around a circular structure, using rotated text labels. The code employs `d3.stratify()` to convert flat CSV data into a hierarchy and `d3.tree()` with a custom `project()` function to map Cartesian coordinates to radial positions. Curved link paths connect parent and child nodes, while rendered SVG elements distinguish internal and leaf nodes. The visualization reads from `operations.csv` and uses D3 v4 within a React-based setup.

Fork of Tree3

This interactive D3.js tree diagram visualizes a hierarchical dataset of failure codes and priorities from a CSV file, with nodes representing categories like functional issues and process errors. The layout uses a collapsible tree structure where clicking a node toggles its children, enabling exploration of nested relationships. Built with D3 v3, it employs `d3.layout.tree` for positioning, `d3.svg.diagonal` for curved links, and SVG transitions to animate nodes and links as the hierarchy expands and collapses. The visualization renders text labels and circles styled with CSS, with data loaded asynchronously via `d3.csv`.

Operation Tree

This example shows a collapsible operation tree for electric vehicle modes, with color-coded nodes distinguishing normal and fault operation modes alongside their sub-modes. Users can click nodes to expand or collapse child branches, triggering animated transitions as nodes reposition. Built with D3 v5, the visualization uses `d3.tree` and `d3.hierarchy` for layout and `d3.linkHorizontal` for curved links, while `d3.zoom` enables panning and zooming. Nodes are rendered as SVG rectangles with labels, and data comes from a static JavaScript object defining the hierarchical structure.

This interactive graph visualizes a hierarchical dataset, starting with a root "flare" node and expanding through categories like "analytics," with the force-directed layout used to position nodes. Built with D3 v3, it uses `d3.layout.force()` to simulate physical forces, with node size proportional to the `size` property from the `graph.json` file. The visualization demonstrates how clicking on a parent node toggles the display of its children, allowing users to explore the tree structure. Nodes are rendered as SVG circles with labels, and links are drawn as lines, with color coding distinguishing collapsed, expanded, and leaf nodes.

This example displays a hierarchical dataset as an interactive dendrogram or tree, allowing toggling between the two layouts via radio buttons. The visualization is built with D3 v4’s `d3.tree()` and `d3.cluster()` layout algorithms, animated with `d3.transition()` for smooth morphing of node positions and link paths. Data comes from `treedata.csv` containing a hierarchical structure with leaf values. The SVG rendering uses colored circles for internal and leaf nodes, with text labels and cubic Bézier diagonal links, all within a React framework.

Untitled

This example shows a collapsible tree diagram of a small hierarchical dataset with four labeled nodes. Users can click nodes to expand or collapse their children, triggering smooth animated transitions of the SVG links and circles. The code uses `d3.hierarchy`, `d3.tree`, and `d3.selectAll` with transition methods to update node positions and draw curved diagonal paths. Node and link styling is applied via CSS classes, with collapsed nodes rendered in lightsteelblue.

This example visualizes the hierarchical structure of a dataset from `data.json` as a radial tree. The layout is computed using a force-directed simulation via D3’s `d3.forceSimulation` API, which positions nodes based on repulsion and attraction forces. The root node is highlighted, and hover interactions reveal child node details and highlight the direct ancestry path, while non-related nodes are dimmed. The visualization is rendered using D3’s SVG-based `d3.geoPath` for the curved links, with the entire graph adapting to window resizing.
