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.

AI-generated description

This is a tree diagram that used data from a csv file. It has been written with d3.js v4 and is based on the simple horizontal version here

This is designed to be used as part of documenting an update to the book D3 Tips and Tricks to version 4 of d3.js.

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.

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 v7

This example shows a hierarchical tree diagram built from a CSV dataset, using D3.js v7. The diagram visualizes parent-child relationships, with nodes representing items like "Top Level" and "Level 2: A," connected by curved links. It uses the `d3.tree` layout, `d3.stratify` to convert flat CSV data into a hierarchy, and `d3.hierarchy` to map the structure. The SVG output positions nodes and draws the tree with circles and text labels, styled via CSS.

Tree diagram using flat data with v4

This tree diagram visualizes hierarchical relationships from flat, parent-child data, rendering nodes and curved links in an SVG. It uses d3.stratify() to convert the flat data into a hierarchy, then applies the d3.tree() layout to position nodes. The code assigns node names via treeData.each(), draws paths for links with cubic Bézier curves, and styles circles and text for internal and leaf nodes. The example demonstrates d3 v4’s approach to handling non-nested data, with margins and dimensions set explicitly for the SVG output.

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.

Collapsible Tree Example

This collapsible tree diagram displays hierarchical data from a CSV file, with nodes positioned by depth and connected by curved links. The visualization loads flat data from `treedata.csv` and converts it into a tree structure using a name-to-parent mapping. Rendered with SVG, it employs the `d3.layout.tree` and `d3.svg.diagonal` APIs from d3.v3 to compute node positions and draw paths. Each node appears as a white circle with a steelblue stroke, labeled with its name, while the layout normalizes node depths to 180 pixels per level.

Tree layout

This example uses D3.js version 4 to render a hierarchical tree layout from CSV data. The visualization shows nodes connected by curved paths, where node labels display different data fields depending on their depth level. The tree uses `d3.tree()` to compute positions and `d3.hierarchy()` to structure the nested data. A React version is included, and an alternative HTML file demonstrates dynamic resizing with the `clientWidth` and `clientHeight` properties.
