Multiple SVGs

transitions

This example animates a set of circles as they move and resize across a wide SVG canvas. Five circles, each driven by values from a static JavaScript array, shift their horizontal, vertical, and radius properties over a four-second duration. The code uses D3's `select()` to append the SVG and builds the animation with the `transition()` API, chaining `.duration()`, `.attr()`, and opacity settings. The circles are rendered as semi-transparent blue shapes, with the initial data divided by a constant factor within the external data module.

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.

d3js workshop - circles

Three circles are rendered in an SVG, with a red fill and a staggered transition that delays each circle’s color change and radius increase by one second per circle. The example demonstrates D3’s data join, binding an array of numbers to circle positions, and uses `transition().delay()` and `transition().duration()` to animate style and attribute changes over two seconds. The code explicitly appends an SVG element, selects circles via `d3.select`, and applies transitions to fill, radius, and vertical position, showing basic animation and data-driven updates with D3 v3.

Multiple SVGs with Functio/n

A grid of 400 blue circles fills a red SVG canvas, demonstrating the repetitive creation of shapes across multiple SVG elements. The code uses D3 v5's `select` to append a single SVG and then loops with nested `for` statements to place circles at computed x and y coordinates. A custom `mySvg` function sets the width and height, while a margin group (`g`) is defined but left unused. The example shows procedural generation of geometric patterns in D3, with circle radius and spacing derived from the SVG dimensions.

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.

Circle overlap

Ten concentric circles, colored from black through green, blue, yellow, orange, purple, teal, and green to yellow and finally red, are drawn inside an SVG. The circles expand outward in radius from 20 to 200, with their horizontal positions also set to their radius, creating a diagonal stack. The visualization uses d3.select to append a group, scales it by 1.5, and binds the data array via d3’s data join, setting circle attributes for radius, position, fill, stroke, and stroke width.

d3js workshop - circles

This example demonstrates how to animate three circles on an SVG canvas using D3.js version 3, showing how data binds to elements and transitions update their appearance. It creates an SVG of 720 by 120 pixels, binds a simple array of three numbers to circle elements, and positions them horizontally based on their data values. The visualization uses chained `transition()` methods with configurable `duration()` and `delay()` to animate the circles’ fill color to red, and also applies radius and vertical position changes. The code relies on D3’s data-join pattern (`selectAll`, `data`, `enter`) and shows how multiple transitions can be sequenced with per-element delays.

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.
