Tree diagram from csv using v5

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 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 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 v5

This example shows a horizontal tree diagram built with D3 v5, displaying hierarchical data from a flat array of name and parent fields. It converts the flat data into a hierarchy using `d3.stratify`, then applies the `d3.tree` layout to position nodes. The SVG rendering includes curved `path` links between nodes, with circles for nodes and labels positioned to the right for leaves and left for internal nodes. The code uses `d3.hierarchy` and D3 selections to append elements, styled with CSS for node fills and link strokes.

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 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 v5

This example presents a vertical tree diagram built with d3.js v5, displaying a small parent-child dataset with nodes labeled "Top Level," "Level 2: A," and their descendants. It shows the hierarchical structure through SVG rendering, with circular nodes connected by curved paths. The code uses `d3.hierarchy` to process the nested data and `d3.tree()` to compute layout positions. Links are drawn as cubic Bézier curves via path string generation, while each node is a group containing a circle and centered text label, with internal nodes styled slightly differently from leaves.

Tree diagram loading external json with v5

This example shows a tree diagram that visualizes hierarchical data loaded from an external JSON file. The diagram uses a horizontal layout where parent nodes appear on the left and child nodes extend to the right, with circular markers and text labels for each node. The visualization is rendered as an SVG, built with d3.js v5, using the `d3.tree()` layout algorithm, `d3.hierarchy()` for structuring parent-child relationships, and `d3.json()` for asynchronous data loading. The data itself is a simple family tree with a top-level node, two second-level nodes, and two leaf nodes.
