This animation shows a red wave packet propagating back and forth across an SVG canvas, wrapped in a semi-transparent blue envelope that traces the pulse’s amplitude. The motion is driven by an explicit time loop with a constant step, reversing direction when the packet reaches the graph’s edge. The code uses d3.line and d3.area with d3.curveBasis to render the signal and envelope paths, while a d3.transition with duration 20 and d3.easeLinear repeatedly restarts itself to update the data. D3 v4 scales map input ranges to screen coordinates.

Circle Wave

Three concentric, overlapping circles in cyan, magenta, and yellow continuously deform into a shifting wave pattern on a dark background. A slider labeled “Frequency” adjusts the speed of the oscillation, while the shapes are drawn as closed radial-line paths that update every frame. The code uses D3 v4’s `d3.radialLine`, `d3.curveLinearClosed`, and `d3.timer`, with the stroke colors blended via CSS `mix-blend-mode: darken`. The radius of each point is computed from a cosine function and a time-based term, creating the rhythmic, breathing motion.

Wave animation with d3

This example animates a dynamic wave of circles that continuously change in number, position, and radius across the screen. The visualization uses D3 v7’s `select` and `range` functions to generate positional data based on a cosine function, with a time variable `t` incrementing every frame. The circles are rendered as SVG elements and updated via D3’s `join` pattern, which efficiently manages enter, update, and exit selections. The animation runs at 60 frames per second using `setInterval`, creating a smooth, oscillating motion that responds to the evolving data.

Fork of Fork of Bouncy Wave

This example shows a dynamic wave animation composed of circles connected by a line, where both the circles’ positions and radii oscillate sinusoidally over time. The visualization continuously updates at 60 frames per second using `setInterval`. The code builds the dataset with `d3.range` and `Math.sin`, then renders SVG elements via D3’s `selectAll` and `join` pattern. It uses `d3.line` to generate the connecting path and updates circle attributes such as `cx`, `cy`, and `r` on each tick.

Wave Motion

A grid of faint circular outlines fills the background, representing water parcels in a calm state. Overlaid on this, bright dots travel along the perimeters of each ring, rotating in coordinated, wave-like patterns that ripple across the canvas. The animation uses a d3-timer to update the rotation angle for each dot, with position and rotation calculated from the grid index and elapsed time. Two layered Canvas 2D contexts render the static rings and the moving dots, with devicePixelRatio scaling for sharp display on high-DPI screens.

Wave with gradient

This example animates a growing wave of circles across the screen, with each circle’s size and vertical position modulated by a sine function over time. The circles are colored with a radial gradient that transitions from purple to white. Written in D3.js, the code uses `select`, `range`, and a join to append new circles each frame, while `transition` and `easeLinear` control the size change. The animation runs on a `setInterval` at 60fps, incrementally adding circles until they fill the viewport width, then resetting.

Circle Wave

Three semi-transparent rings in cyan, magenta, and yellow form undulating circular waves around a shared center. Each ring’s radius oscillates based on a cosine function modulated by time, creating a continuously morphing, layered pattern with a darken blend mode. The animation uses `d3.radialLine` to generate the wave paths from an array of 200 angles, while `d3.timer` drives the redraw of each SVG path every frame. The code relies on D3 v4’s SVG rendering and the `mix-blend-mode` CSS property to composite the overlapping strokes.

Sine Wave

This visualization displays a sine wave rendered as an SVG path. The wave is generated using D3.js version 5, with the `d3.line` generator and `d3.scaleLinear` for mapping data points to screen coordinates. The animation updates the wave’s phase over time using `d3.interval`. The example demonstrates how to build interactive, time-based data visualizations with D3’s core modules, including axis creation via `d3.axisBottom` and `d3.axisLeft` for reference lines.

Fork of Bouncy Wave

This interactive visualization renders a sine wave as a sequence of thick-stroked, white-filled circles connected by a black path, all drawn as SVG. The animation updates at 60 frames per second, with the number of circles oscillating between 5 and 15 and each circle’s vertical position, radius, and the connecting line’s shape shifting based on a time parameter. The code uses the d3 `select`, `range`, and `line` APIs to generate data and append SVG elements, with the `selection.join` method synchronizing the changing dataset to the rendered shapes.
