This example demonstrates a looping transition in which a steelblue circle travels from the left side of an SVG canvas to the right and back again, repeating indefinitely. It shows how to chain two sequential transitions on the same element by using the `transition` API from d3-transition, with the `.duration()` method controlling the 2000-millisecond timing for each leg. The circle’s position is set with `.attr('cx', ...)` and `.attr('cy', ...)`, and the `on("end", repeat)` callback restarts the entire sequence, creating seamless motion across the 960×500 viewport.

AI-generated description

This is a demonstration of looping transition chaining using d3.js v5.

The circle moves from left to right and then back again so that it starts and ends in the same state and then we instruct the transition code to repeat itself.

This graph is part of the code samples for the update to the book D3 Tips and Tricks to version 5 of d3.js.

Looping a transition in v7

This example demonstrates a looping transition animation in d3.js v7. A single steel-blue circle moves horizontally across an SVG canvas, traveling from the left edge to the right and back again. The animation uses the `d3.transition` API, chaining two successive `.transition()` calls with a duration of 2000 milliseconds each. Upon completing the return trip, an `.on("end", repeat)` callback triggers the entire sequence to start over, creating an infinite loop. The circle’s position is set via the `cx` and `cy` attributes.

Looping a transition in v6

A single steelblue circle loops a transition chain across a 960-by-500 SVG canvas in D3 v6. A custom `circleTransition` function appends the circle, then chains `.transition()` calls with `.duration(2000)` to move it from x-coordinate 40 to 920 and back. The `.on("end", repeat)` callback restarts the same chained movement, creating an infinite back-and-forth animation. This example demonstrates transition chaining and callback-driven repetition using d3-transition.

Looping a transition in v4

A steelblue circle loops horizontally across a 960-pixel-wide SVG canvas, moving right for two seconds and then left for two seconds in a continuous cycle. The example demonstrates d3-transition chaining in d3.v4 using `.transition()` and `.duration()` to animate the `cx` attribute, with the `on("end")` event triggering the repeat function. This serves as a starting template for building more complex looping animations in D3 version 4.

Simple transition chaining in v5

A blue circle moves across an SVG canvas in three sequential transitions, each lasting four seconds. First, its horizontal position animates from the left side to the right side; then its radius grows from 20 to 40 pixels; finally, its fill color changes from blue to red. This example demonstrates transition chaining in D3 v5, where calling `.transition()` after a previous transition schedules the next animation to begin automatically. It uses D3’s `transition` API with `.duration()` and `.attr()`/`.style()` methods.

Simple transition in v5

A simple transition moves a blue circle horizontally across an SVG canvas in d3.v5. The example demonstrates the d3-transition API by animating the circle’s `cx` attribute from 40 to 920 pixels over 4000 milliseconds. The code builds the scene by appending a circle to the SVG, setting its initial position and fill, then chaining the transition with a duration. It uses `d3.select` to target the body and `transition()` to interpolate the positional change.

Simple transition chaining in v4

A circle begins on the left side of an SVG canvas and performs three sequential transitions: it moves horizontally to the right over four seconds, then doubles its radius over another four seconds, and finally changes its fill color from blue to red. The example demonstrates the chaining of transitions in d3.js v4, where each call to `transition()` queues the next animation stage after the previous one completes. The scene renders as animated SVG, using the `d3.select`, `append`, and `attr`/`style` methods to construct and modify the circle element, with transition durations set in milliseconds.

Simple transition chaining in v6

A circle demonstrates sequential transition chaining in d3.js v6, moving from left to right, then expanding its radius, and finally changing fill color from blue to red. Using the d3-transition API, the code applies three consecutive `.transition()` calls, each with a 4000-millisecond duration, to an SVG circle appended to the body. The example shows how transitions queue and execute in order, rendering the animation directly in SVG.
