A radial tree visualization displays a hierarchical dataset as curved links radiating from a central root node, with leaf nodes positioned along the outer circumference. The code uses D3 v4's `d3.tree()` layout with a radial size, `d3.stratify()` to parse hierarchical CSV data, and `d3.linkRadial()` to generate the bezier paths. SVG circles mark nodes, while panning and zooming are enabled via the `d3.zoom()` API. The flare.csv dataset provides the hierarchy, and the rendering is entirely SVG-based with light blue translucent links.

RADIAL TREE 2

This radial tree visualization displays a hierarchical dataset from a CSV file, using a circular layout where branches extend from a central root. The visualization supports panning and zooming interaction, allowing users to explore the hierarchy. Built with D3 v4, the code uses `d3.stratify`, `d3.tree`, `d3.linkRadial`, and `d3.csv` to process and render the data as an SVG. Nodes are drawn as circles with text labels, and links are rendered as curved paths with light blue strokes. The tree is positioned within a large SVG canvas, with labels rotated to follow the radial structure.

Fork of RADIAL TREE 2

This radial tree visualization uses a hierarchical dataset (flare.csv) to display the nested structure of categories like analytics, animate, and query, with each node positioned by angle and radius from the center. The D3.js v4 code constructs the tree using `d3.stratify` and `d3.tree`, then renders SVG paths with `d3.linkRadial` for links and circles with text labels for leaves and internal nodes. The layout is static, with no panning, zooming, or interaction implemented in the visible script.

A radial tree visualization displays the hierarchical structure of the Flare dataset, with nodes arranged in concentric circles around a central root. The code uses D3 v4’s `d3.stratify` to parse CSV data, `d3.tree` for layout, and `d3.linkRadial` to draw curved links. Panning and zooming interactions are enabled via D3’s `zoom` behavior, while SVG circles and text labels with rotation show node names.

RADIAL TREE 3

This radial tree visualization displays a hierarchical dataset of part numbers and associated values, branching from a single root node. The layout uses D3’s `d3.cluster` to arrange nodes radially, with curved paths rendering parent–child links. Panning and zooming are supported via D3’s `zoom` behavior, while node labels are rotated to follow the radial angle. Data is loaded from a CSV file and processed with `d3.stratify` to build the tree structure, rendered as SVG.

This radial tree visualizes the hierarchical structure of the Flare dataset, showing parent-child relationships as curved links emanating from a central root. The SVG rendering uses D3 v4’s `stratify` and `tree` layouts with `linkRadial` for path generation, mapping each node to an angular and radial position. Panning and zooming interactions are enabled via D3’s `zoom` behavior. Leaf nodes appear as gray circles, while internal nodes are darker, and text labels rotate to align with the radial layout. The data originates from a CSV file containing node IDs and values.

RADIAL TREE

This radial tree visualization displays a hierarchical dataset, such as a world geography or an engineering part structure, with nodes arranged in a circular layout. The code uses the D3.js v4 library, specifically the `cluster()`, `hierarchy()`, and `zoom()` APIs, along with SVG rendering. The visualization shows how the hierarchy branches outward from the root, with text labels positioned and rotated based on depth and angle. It also includes panning and zooming interaction to explore the tree structure, with the data loaded from a JSON file.

Fork of RADIAL TREE 2

A radial tree diagram visualizes hierarchical data from a CSV file, positioning the sun at the center with planets and moons radiating outward as labeled circles. The visualization uses a D3 v4 layout with `d3.stratify` to build the hierarchy and `d3.tree` for radial positioning, rendering SVG paths for links and nodes. Node labels rotate tangentially around the tree, while an internal/leaf distinction colors parent nodes differently. Data loads from `flare.csv` via `d3.csv`, and the custom `radialPoint` function converts polar coordinates to Cartesian for node placement.

Fork of RADIAL TREE 2

This radial tree visualization displays the hierarchical structure of the Flare dataset, with each node positioned along concentric rings radiating from the center. The data originates from a CSV file containing id and value fields, where leaf nodes are sized by their numeric values and categories branch outward. Built with D3 v4 and rendered as SVG, the visualization supports panning and zooming for interactive exploration of the hierarchy. The layout uses curved links and circular node placement to depict parent-child relationships, with the root node at the center. Text labels are dynamically hidden or shown based on zoom level to reduce visual clutter. The chart is a direct adaptation of Curran Kelleher’s World Countries Hierarchy block, demonstrating hierarchical data representation through a radial tree layout.
