Four colored arc segments rotate continuously around a central point, changing their start and end angles to new random positions every few seconds. The animation uses D3 v4’s `d3.interval` to trigger periodic updates, and each transition relies on `transition.attrTween` with a custom `arcTween` function that interpolates between angle values using `d3.interpolate`. The SVG paths are generated by a `d3.arc()` generator, with each arc assigned a fixed inner and outer radius, forming concentric rings. The data is procedurally generated JavaScript, with random start angles and arc lengths derived from a random score.

AI-generated description

This little animation is used within the overview sneak-peek animation of the Stitch Fix Algorithms Tour. See Mike Bostock's heavily-commented Arc Tween example for an explanation of arc tweens in general. This animation is made only slightly more complex by the use of four arcs and by varying both the start and the end points.

Animated Arcs

Four concentric animated arcs rotate continuously around a central point, each with a distinct color and its own random start and end angles. The arcs periodically change their sweep length and position, creating a dynamic, looping visual rhythm. Built with D3 v4, the example uses SVG paths and `d3.interval` to trigger transitions, while `transition.attrTween` and `d3.interpolate` smoothly animate each arc’s angles. The code generates random data for four arcs with varying radii and colors, drawing them with the `d3.arc` shape generator.

arc tween example

An animated arc chart demonstrates pie-segment transitions using D3 v4’s `transition.attrTween`. A white foreground arc rotates to a new random angle every few seconds, while a segmented, multicolored ring around it sequentially fills or empties its sections. The code defines arc generators via `d3.arc`, binds data from a fixed array, and computes path interpolations between angles using `d3.interpolate`. SVG elements render the background ring and active arcs, with transitions triggered by `d3.interval`.

animated arc

This example animates a set of orange arc segments that expand and fade out over time, creating a wave-like effect. The visualization uses SVG paths generated by the `d3.arc` generator, with a `clipPath` (a 200×200 rectangle) to constrain the arcs' visibility. A single transition, invoked via `transition.attrTween`, interpolates each arc's inner and outer radii from 0 to 300, while `style("opacity", 0)` fades them out. The animation runs over 4 seconds with staggered delays of 200 milliseconds per arc, using `d3.easeLinear`. Ten arcs are created from an array of empty objects, and the code relies on D3 v4.

Arc Tween

The visualization demonstrates smooth animated transitions of arc segments using D3 v4’s `transition.attrTween`. It shows a circular foreground arc that repeatedly updates its angle, while a secondary set of colored arcs animates inward and outward between paired data values. The `d3.arc` generator builds SVG path strings with bound start/end angles, and the tween interpolates the endAngle over 750 milliseconds for the main arc and 1750 milliseconds for the colored segments. Random angle targets drive the main arc, while paired arrays (e.g., `[0, 0.25, 0.4, 0.65, 0.9, 1]`) control the secondary arcs’ expansion and contraction.

Arc Tween

A donut chart demonstrates arc transitions using D3 v4. An orange foreground arc repeatedly animates to a new random end angle, while a static gray background arc represents the full circle. The code uses `transition.attrTween` with a closure that interpolates between the current and target end angles via `d3.interpolate`, updating the bound datum before recomputing the SVG path with `d3.arc`. Rendering is SVG, with transitions triggered every 1.5 seconds by `d3.interval`.

2019 Arc Tween

A circular gauge displays a background arc and an orange foreground arc representing a value, which updates to a new random angle every few seconds. The animation uses a custom `transition.attrTween` on the `d` attribute, interpolating the endAngle in data space via `d3.interpolate`. The arc path is computed with `d3.arc`, and the transition duration is set to 100,000 milliseconds, creating a smooth, continuous rotation.

Arc

This example visualizes the four possible arc paths defined by the SVG elliptical arc command, using D3.js v6 to generate paths from a fixed start point, specified radii, a rotation angle, and four combinations of the large-arc and sweep flags. Each path is rendered in a distinct color from `d3.schemeSet3` and styled with a thick stroke, without any fill. The arcs are drawn in an SVG container and offset via a transformation, demonstrating the geometric differences between the arc flag choices in a clean, minimal setup. The dataset `socfb-Caltech36.json` is referenced but not used in the rendering logic.

This example demonstrates how D3.js v4 uses SVG to render circles with varying radii, each overlaid with a red arc path generated by the `d3.arc()` generator. It shows the relationship between circle size and arc geometry, with arcs using random start angles and a fixed end angle. The code binds an array of radius values to SVG circles, then appends a path element to each, applying the arc generator with an outer radius based on the data and a transform to position it. The visualization uses a simple data-driven approach with static positioning, filling circles in BlanchedAlmond with red strokes.
