This interactive visualization builds a circular synthesizer where each of the 16 beats is a rotating segment containing concentric pitch arcs. Users click or hover over arcs to toggle notes on and off, with four states cycling through white, blue, red, and green. The visualization uses D3’s `d3.svg.arc` and linear scales to map pitch frequencies to radii, while an audio context schedules oscillators for each active note. A `setInterval` loop advances the beat, highlighting the current segment in purple and triggering sounds through the Web Audio API’s `createOscillator` and `createGainNode`.

Circle Piano

A circular piano keyboard displays seven musical notes repeated across a ring, with black keys for sharps and white keys for naturals. Hovering or touching a key expands its arc outward while simultaneously playing a square-wave tone via the Web Audio API. Built with D3 v4, the visualization uses `d3.pie` and `d3.arc` for geometry, `transition.attrTween` for smooth animation, and SVG for rendering.

Circular Layout (Arc)

A circular layout of concentric arcs radiates outward from a central point, with each arc’s color shifting from brown to steel blue as its radius increases. The visualization encodes two linear scales—one mapping radius size and another mapping fill color—onto a grid of 180 rotated groups. Built with D3 v3, the code uses `d3.svg.arc` to generate each path segment, with `innerRadius` and `outerRadius` driven by the same scale. Rotating each group by successive 2-degree increments creates the full circular pattern. The data is generated synthetically via `d3.range`, not from an external source.

Circular Geometric Patterns

This interactive visualization cycles through circular geometric patterns, drawing a series of overlapping circles and a connecting polyline at the center of an SVG canvas. The pattern evolves automatically as a timer increments both the number of nodes and a "skip factor" that determines the angular spacing between points. Built with React and D3 v5, it uses `d3.range`, `d3.line`, and `d3.curveLinearClosed` to generate points along a circle and construct the path, while React's `useState` and `useEffect` drive the animation loop.

animating data cleaner code

This example uses D3 v7 to create an animated, generative visualization of circles. It displays a dynamic sine-wave pattern where 10 to 15 circles move vertically and change radius over time, rendered as SVG elements on a full-window canvas. The animation runs at a 60 FPS interval, with each frame updating the `cx`, `cy`, and `r` attributes of the circles via `selectAll` and `.join`. The periodic motion is computed using `Math.sin` for both position and size, creating a smooth, evolving sine-wave composition.

Arc Piano

The visualization displays a semicircular piano keyboard whose keys extend outward when hovered or touched. It uses a D3 pie layout for the key positions, with custom arc tweening via `transition.attrTween` to animate the radial expansion. The code generates audio tones using the Web Audio API's `createOscillator` and `createGain` nodes, playing a square wave at a computed frequency for each key. The SVG rendering uses D3's `d3.arc` with corner radii and two inner-radius levels to distinguish sharp and white keys.

Sine Wave Circles

A row of white circles animates vertically to form a flowing sine wave. The visualization uses D3 v4 to bind an array of 40 numbers to SVG circle elements, positioning each along the x-axis. A `d3.timer` continuously updates each circle’s y-coordinate based on the sine of its index plus elapsed time, creating the wave effect. The circles are evenly spaced with a fixed radius, rendered on a black background.

Fork of Messing around with Sine Wave Circles

Four overlapping sine waves animate across the screen as rows of filled circles. Blue and crimson circles trace complementary sine and cosine paths, while smaller turquoise and orange circles follow similar curves with tighter spacing. The visualization uses D3 v7’s `d3.timer` to update each circle’s `cy` attribute based on a time offset, rendering 200 circles per wave in an SVG. It demonstrates periodic motion through D3’s data-join and selector methods.

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.
