This circle-packing diagram visualizes the hierarchical structure of the Flare dataset, with nested circles representing categories and subcategories. Circle size encodes the summed value of each node. The visualization uses D3 v5’s `d3.stratify` and `d3.pack` to compute the layout, and `d3.scaleSequential` with `d3.interpolateMagma` to color circles by depth. Hovering highlights a node’s ancestors using the `d3.selectAll` and class toggling. SVG renders all elements, with leaf labels clipped via `clipPath`.

D3 v5 Circle-Packing

This visualization uses a circle-packing layout to display the hierarchical structure of the Flare software project’s classes and packages, with circle size encoding the value of each node. The example is implemented with D3 v5 and renders as SVG, using `d3.stratify` to build the hierarchy from a CSV file and `d3.pack` to compute the nested circle positions. Circle colors are mapped by depth using a sequential magma scale, and interactive mouseover highlighting is applied through class toggling.

D3 v5 Circle-Packing

This example implements a circle-packing visualization using D3 v5, displaying a hierarchical dataset from the Flare library. The diagram shows a nested arrangement of circles, where each circle represents a data node, with its size proportional to a value and color indicating depth in the hierarchy. Built with D3’s `d3.stratify` and `d3.pack` APIs, it renders to SVG, applying a sequential magma color scale. Interactive mouseover highlights ancestor nodes, while leaf labels are clipped via `clipPath`, and tooltips show the node ID and value.

Circle-Packing

This example visualizes the hierarchical structure of the Flare dataset using circle packing. Each node is represented as a circle, with leaf nodes sized by their value and grouped by their parent categories. The visualization uses D3 v4’s `d3.stratify` to build a hierarchy from the CSV and `d3.pack` to compute the circular layout. SVG circles are colored with a sequential magma scale based on depth, and hovering highlights the ancestors of a node via a CSS class and the `d3.selectAll` method.

D3 v4 Circle-Packing

This example shows a hierarchical circle-packing layout of the Flare software package’s class hierarchy, with each node’s size proportional to its value and color mapped to depth. Using D3 v4’s `d3.stratify` to build the hierarchy from CSV data and `d3.pack` for layout, circles are rendered as SVG groups. Interactivity highlights all ancestor circles on hover via the `d3.selectAll` and `classed` methods, while leaf labels are clipped to their circles.

Fork of D3 v5 Circle-Packing

This D3 v5 circle-packing visualization displays the hierarchical structure of the Flare software system, using circle size to represent the number of metrics for each module. The graph is built from a CSV file using `d3.stratify()` and `d3.pack()`, with node depth encoded through the `d3.scaleSequential(d3.interpolateMagma)` color scale. Circles are rendered as SVG elements, with clip paths and tspan text for leaf labels, while hovering highlights the ancestor chain via the `node--hover` class.

Trying circle packing VI

This circle packing diagram visualizes the hierarchical structure of the Flare dataset, with nested circles representing the data hierarchy and color encoding depth via d3.scaleSequential with interpolateMagma. The visualization uses d3.pack, d3.hierarchy, and d3.format to compute and display node values, while the Observable stdlib's DOM.uid generates unique identifiers for clipping paths that constrain text labels to leaf circles. The SVG rendering includes interactive tooltips showing ancestor paths and values, with the code loaded from @observablehq/flare via require().

Fork of D3 v5 Circle-Packing Testing

This visualization shows a circle-packing layout of the Flare software package’s class hierarchy, using nested circles to represent the data’s hierarchical structure. The code loads data from `flare.csv` with `d3.csv`, processes it with `d3.stratify`, and computes the layout using `d3.pack`. Circles are colored by depth using `d3.scaleSequential` with the magma interpolator, and the visualization is rendered as SVG. Hovering highlights a node’s ancestors by toggling a `node--hover` class.

D3 v5 Circle-Packing

This visualization shows a hierarchical dataset as nested circles, with each circle’s size encoding a numeric value and its color representing depth in the tree. Built with D3 v5 and rendered as SVG, it uses `d3.stratify` to convert the tabular flare.csv data into a hierarchy, `d3.pack` for layout, and `d3.scaleSequential` with `d3.interpolateMagma` for coloring. Hovering highlights a node and its ancestors via the `mouseover` and `mouseout` events.
