A hierarchical circle-packing visualization displays the distribution of militant organizations across ideological categories and time periods. The code uses D3.js to produce a packed circle layout, encoding each organization as a leaf node with a clipped text label, while internal nodes represent hierarchical groupings. Data is sourced from a JSON file with a nested structure. The visualization is rendered using D3’s `pack` layout, `d3.group`, and SVG elements, with circles colored by tree depth and a drop shadow filter applied for visual separation.

A hierarchical bubble chart visualizes the distribution of political organization names, categorized by ideology (such as "armed," "communist," "islam"), then by decade, and finally by geographic region. The circles are sized and packed according to the nested data structure using D3’s `pack` layout. The visualization uses `d3.group` to organize nodes by depth, applies drop shadows via an SVG filter, and labels leaf nodes with clipped text. The data originates from the provided `data.json` file, which details organization entries and their associated years.

Fork of Untitled

This visualization shows a hierarchical dataset of political and armed groups using a circle-packing layout. It displays how groups are nested within categories like "armed," "communist," and "islam," with each leaf labeled by its name. The code uses D3’s `pack` function to compute the circles, then renders them as an SVG with drop shadows, clip paths, and wrapped text. The color scale encodes the tree depth, and hover tooltips reveal the full path and value. The data originates from a `data.json` file, though the accompanying HTML also loads a Google Charts Sankey diagram from pre-processed rows.

Untitled

This visualization displays a hierarchical dataset of political organizations, grouped by categories such as "Armed," "Communist," and "Islam," and filtered by the years they were active. It uses a sankey diagram to show the flow from these top-level categories down to specific organization names. The code loads data from a local `data.json` file and renders it using the Google Charts Sankey package alongside D3.js (v5). The diagram is displayed in a large, wide container to accommodate the many connections between categories and individual groups.

Circle Packing

This visualization displays a hierarchical dataset as nested circles, using area to represent the number of descendants in each node. Color distinguishes between constrained and unconstrained nodes, with constrained items shown in gray and unconstrained ones in blue. The layout is computed using D3’s `pack` algorithm, which positions circles within a viewport sized to the browser window. Data is loaded from `data.json` via D3’s `json` function, then processed with `hierarchy` and rendered as SVG `<circle>` elements, with white strokes providing visual separation between adjacent circles.

Untitled

A hierarchical tree chart displays nested data from `data.json`, organizing entries by organization, armed group, year, city, and province. The visualization uses D3.js’ `tree` layout with `linkHorizontal` paths and zoom functionality, rendering each node as text with font sizes scaled by depth for readability. The data, which includes armed forces groups and their locations, is loaded via `json()`, and interactive panning and zooming are enabled through D3’s `zoom` API.

Untitled

A zoomable circle-packing visualization displays hierarchical data as nested circles, with an initially clicked root (`assault`) revealing child nodes labeled “man,” “information,” “anyone,” and “area.” Built with React and D3 v4, it uses `d3.pack`, `d3.hierarchy`, and `d3.interpolateZoom` to animate transitions between levels, while `d3.scaleLinear` with HCL interpolation colors the circles. Clicking any circle zooms into its subtree, fading labels in and out, all rendered as SVG elements in a 900×900 viewport.

Untitled

This interactive visualization displays a hierarchical tree as a circular packing layout, where nodes are sized proportionally to their values. The code uses the D3.js library (v6.7.0) with its `pack` and `hierarchy` APIs to compute node positions, and transitions to animate changes. Clicking a parent node collapses or expands its children, triggering a re-layout. The SVG renders nodes as circles with labels, and blue directed links with arrowheads connect specific nodes across the hierarchy, based on a `links` array in the data.

This interactive visualization uses a circular packing layout to display a hierarchical dataset from the file `flare.json`. The code employs D3.js v4, React, and SVG with animation, leveraging `d3.hierarchy` to aggregate leaf sizes and `d3.pack` to position circles. Clicking on a node triggers a smooth zoom transition via `d3.transition` and `interpolateZoom` to focus on that subtree, while text labels fade in and out based on parent relationships.
