Two buttons trigger the same animated update for a small set of circles, moving each circle’s center and radius to new values over two seconds. The visualization shows three red circles on an SVG canvas, with the animation smoothly interpolating their positions and sizes via D3’s `.transition()` and `.attr()` methods. The data consists of hardcoded JavaScript arrays of `x`, `y`, and `r` values, and the code uses D3 v4’s selection `.enter()`, `.merge()`, and `.transition().duration()` to handle the state change.

circle dance

Two buttons trigger the animation of three red circles to new positions. The circles move between two predefined sets of coordinates over a two-second duration, demonstrating basic data updates in D3.js. The visualization uses D3 v4’s SVG rendering and the `transition()` method with a duration parameter to animate the changes. The code defines two data arrays containing `x`, `y`, and `r` properties for the circles, and the buttons call the `updatePoints` function to apply the new data.

circle dance start

This example presents a simple interactive D3.js v4 visualization of two sets of points. The interface displays three circles at distinct positions and radii, with two "Update" buttons that trigger a user-defined `updatePoints` function. The code creates an SVG canvas using `d3.select("body").append("svg")` and defines two point arrays (`points1` and `points2`) containing x, y, and radius values. Although the update function is currently empty, the structure demonstrates how to bind button clicks to replace or redraw the circular elements, serving as a minimal template for dynamic positional data updates.

Circles with Animation

Eleven concentric circles pulse sequentially from a central point, expanding and collapsing in three alternating colors: red, green, and yellow. Each circle animates its radius from zero up to a multiple of its index times ten pixels, then shrinks back. The visualization uses D3 v5 selections with chained `transition().duration()` calls to animate SVG `circle` elements, setting radius, position, fill, and stroke attributes. The data array of indices 0 through 10 drives the size progression, while CSS opacity at 0.1 gives the overlapping circles a translucent, layered effect.

rotating the circles

Three SVG circle groups swap positions and sizes in a looping rotation, with circles entering and exiting as the dataset cycles through three IDs. The animation uses D3 v4 selections with keyed data joins, `transition()` for staggered movement, and `attr("r")` to grow new circles from radius zero while shrinking departing ones. The example demonstrates D3’s enter, update, and exit pattern with data-driven `cy` coordinates and a one-second duration, all rendered in animated SVG within a minimal blockbuilder setup.

D3 Circle animation

Eight red circles animate simultaneously along straight paths within a large circular outline on a white background. Each circle travels from a point on the circle’s perimeter toward the center, with staggered start times creating a rotating, pulsing effect. The animation uses SVG’s `animateMotion` element with the `path` attribute and staggered `begin` times, while the overall layout and styling come from static SVG markup with `mix-blend-mode: hard-light`. The example relies solely on native SVG animation, not D3’s JavaScript APIs.

circles

Three concentric circles rotate continuously around a shared center, with red and green fills determined by radius and blue radial lines indicating rotation. The visualization uses D3 version 6 to append SVG `circle` and `line` elements inside `g` groups, updating their `transform` style via a JavaScript `setInterval` timer. A CSS `@keyframes` animation on hover triggers an additional 360-degree rotation. The code demonstrates D3’s declarative selection and merging API with `d3.select`, `enter`, and `merge` on an SVG canvas sized to viewport dimensions.
