This example shows a minimalist loading spinner rendered as a single animated arc that rotates continuously around a circular track on a pale green background. The animation uses D3 transitions with a 20-second duration, where `transition.attrTween` interpolates the arc’s `endAngle` from 0 to 2π, and an `on("end")` callback restarts the spin indefinitely. The code builds the shape with `d3.arc()`, setting outer and inner radii relative to the container size, and positions it via an SVG `<g>` transform.

Fork of D3 spinner - 2

A circular loading spinner animation comprises ten evenly spaced blue dots arranged around a light blue SVG canvas. The dots rotate positions and vary their radius and opacity based on a rotating array of angles, creating a wave-like pulse effect. The code uses D3.js selection methods, including `data` joins with enter and update handling, alongside `d3.interval` to trigger periodic rotation of the dataset. All rendering is done via SVG, with parametric circle equations computing each dot’s coordinates.

Spinny

This example visualizes a classic “spinny” loading icon using D3.js version 3. It shows a rotating ring of ten small circles that continuously spin around the center of the screen. The circles are positioned using sine and cosine functions based on a linear angle scale, with their radii varying from larger to smaller around the ring. The animation is driven by `d3.timer`, which updates the rotation attribute of a group element each frame, incrementing the angle by a fixed amount. The visualization uses SVG for rendering and relies on D3’s data join to bind an array of numbers to the circles.

Rainbow spinner

Animated SVG loading spinner renders 181 rainbow-colored arc segments using D3's `d3.arc` and `d3.interpolateRainbow`. The 960×500 canvas orbits the spinner around its center via `d3.timer`, while a clip path continuously stretches a plain arc's angle using `transition.attrTween`, alternating between expanding and contracting to mimic an Android-style loader.

Spinner with d3-component

This example demonstrates how to display a spinner while data is loading and replace it with a bar chart after a simulated fetch. It uses d3-component’s conditional rendering to switch between components, with a local timer driving the spinner’s rotation based on elapsed time. The visualization is rendered as SVG, using D3 transitions with a bounce ease to animate bar heights.

d3 Animation

This example demonstrates a single-circle animation using D3 transitions. The visualization shows a red-outlined circle that starts at the left side of an SVG canvas and moves downward while changing its fill color to green over one second. The code appends an SVG element sized to the browser window, creates a circle with initial x-coordinate 200, then chains a transition with a 1000-millisecond duration to animate the y-coordinate, radius, and fill style. It uses D3 v6's `selection.transition()` and `transition.attr()` methods within a minimal HTML page.

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.
