Tree diagram from csv using v6

This tree diagram visualizes hierarchical data loaded from a CSV file, with nodes representing names and links showing parent-child relationships. The example uses d3.csv to load the flat data, d3.stratify to convert it into a hierarchy, and d3.tree to compute the layout. Nodes are rendered as circles with labels, while curved paths drawn via SVG path elements connect parents to children. The code also assigns CSS classes based on whether a node is internal or a leaf, adjusting text placement and styling accordingly.

Tree diagram from csv using v5

A horizontal tree diagram visualizes a parent-child hierarchy loaded from a CSV file, showing five nodes across three levels from a single root. The D3.js v5 code uses `d3.csv` for data ingestion, `d3.stratify()` to convert the flat table into a hierarchy, and `d3.tree()` for layout. Nodes are rendered as SVG circles with text labels, while curved paths connect parent and child nodes using the `d3.hierarchy` API. The example demonstrates an update to D3 v5 with a simple, readable structure.

Tree diagram from csv using v4

This tree diagram visualizes hierarchical data from a CSV file, showing parent-child relationships with labeled nodes connected by curved links. It uses D3.js v4’s `d3.tree()` layout and `d3.stratify()` to convert flat CSV data into a hierarchy, while `d3.hierarchy()` and `d3.selectAll()` render the SVG nodes and paths. The diagram highlights internal nodes with white circles and steelblue strokes, and positions text labels beside each node. The source data (`treeCsv.csv`) includes names, parents, and ages, though ages are not displayed. The code explicitly handles null parents and uses cubic Bézier curves for link paths.

Tree diagram from csv using v4

This tree diagram visualizes hierarchical data loaded from a CSV file, displaying nodes as white circles with steel-blue outlines connected by curved gray links. The visualization uses d3.v4's `d3.tree` layout, `d3.stratify` to convert flat parent-child records into a hierarchy, and `d3.hierarchy` to map the structure. Text labels appear beside each node, positioned differently for internal versus leaf nodes. The SVG rendering includes CSS styling for node circles, text shadows, and link strokes, following the D3 Tips and Tricks book example.

Simple vertical tree diagram using v6

This simple vertical tree diagram displays hierarchical data with a root node branching into two levels, using circles for nodes and curved paths for links. The visualization is rendered as SVG with D3.js v6, using the `d3.tree()` layout and `d3.hierarchy()` to structure the hard-coded data, then appending groups and paths via `selectAll().enter()`. Node labels are offset above or below circles depending on whether they have children, and internal text includes a white shadow for readability. The code sets explicit margins and dimensions to position the tree within the viewport.

Simple horizontal tree diagram using v5

A simple horizontal tree diagram visualizes hierarchical data with three levels: a top-level root node, two second-level branches, and two leaf nodes. The code uses D3.js v5’s `d3.tree()`, `d3.hierarchy()`, and `d3.select()` APIs to compute the layout and render SVG paths for curved links and circles for nodes, with text labels positioned left or right based on whether a node has children. The diagram is defined by a static JavaScript object `treeData` and styled via CSS classes.

Simple vertical tree diagram using v7

This is a simple vertical tree diagram built with d3.js v7, displaying a small hierarchical dataset with a top-level node, a branching level, and leaf nodes. It shows parent-child relationships using curved links, with internal and leaf nodes styled differently via circles and text labels. The code uses the `d3.tree()` layout and `d3.hierarchy()` to compute node positions, then renders the structure as SVG paths and groups. The data is embedded directly in the script, and the visualization is designed as a starting point for further development.

Tree Layout from CSV

A tree layout visualization reads hierarchical relationships from a CSV file with source-target pairs, such as A1 to A2 and A2 to A3. Using d3.v3, it dynamically builds nodes and links from the data, rendering a tidy tree where parent and child relationships are clearly shown through straight lines and small circles. The example specifically uses d3.layout.tree for node positioning and d3.svg.diagonal for link paths, with a white-stroked node style and black link lines. The SVG output displays a simple three-node chain, illustrating how a flat two-column CSV can be transformed into a structured tree diagram.
