Squares ↔ Hexagons

Gist 00170d49e926de0c3a9a

A grid of small circles and hexagon-like arrangements of rounded orange rectangles animates in a staggered transition. The visualization generates a field of triangular tile motifs, where each tile contains three small circles and three rounded rectangles positioned at their edges. Initially, the rectangles and circles sit at the tile centers; after a delay, they rotate outward to the triangle’s midpoints. Using D3.js with SVG transitions, the code applies `translate` and `rotate` transforms to reposition elements, driven by trigonometric calculations for hexagon geometry. The rendering uses D3 selections and transitions, with data-bound groups and nested arrays to handle multiple coordinates.

squares-around-circles

The animation shows a grid of small circles, each surrounded by four square outlines that continuously expand and rotate. The squares appear to “breathe,” pushing outward and then resetting in a cyclical loop, creating a pulsing, geometric pattern across the screen. The code uses D3.js with SVG paths, leveraging the `transition` and `attrTween` methods for smooth movement. Each square’s position and orientation are calculated from its center point and a side number, updated via functions like `pushLinesOut` and `pointToPath`. The data is generated procedurally, with no external dataset.

Transform Transitions II

A grid of 1,200 small colored squares, each assigned a position via inline CSS `transform` and a hue from `d3.hsl`, reacts to mouseover by flying to the center of the viewport. The selected square scales up and rotates 180 degrees using D3’s `transition().style("transform")`, which interpolates the CSS transform string, then shrinks and removes itself. Built with d3.v4 and `d3.range`, the animation leverages D3’s transform interpolation to smoothly tween translate, scale, and rotate values, while `raise()` brings the active square to the front.

Voronoi Spirals

Randomly placed points generate Voronoi cells that gradually spiral inward, cycling through a Cubehelix color scale over a five-second animation. The d3-voronoi layout computes the initial polygons, then each frame the code shifts a vertex and interpolates a new point along each cell’s first edge, closing the path and filling it with a color based on elapsed time. Rendered on a Canvas via the d3.timer API, this creates a continuous, organic morphing effect.

Transform Transitions

A grid of colored squares animates in response to mouse hovers, demonstrating smooth interpolation between different 2D SVG transforms. Each rect transitions from its original translate to a combined translate, scale, and rotate, then shrinks and fades before being removed. The code uses d3.v3 transitions with `.attr("transform")` to leverage matrix decomposition, automatically decomposing transforms into canonical translate, rotate, scale, and skew components. The visualization is built with a data-joined SVG rect per grid cell, filled with HSL colors based on position, and rendered entirely through D3’s selection and transition APIs.

Rotating Voronoi

Rotating Voronoi shows a black-and-white field of curved cells generated from continuously moving points. Multiple rings of points orbit at different speeds and radii, causing the Voronoi diagram to shift and deform fluidly over time. The animation uses the D3 `d3.geom.voronoi` to compute the cells, clips them against a rectangular boundary, and subdivides each polygon edge into three equal segments before applying the `basis-closed` interpolation to create the smooth, organic curves. The SVG paths are re-rendered each frame with `d3.timer`.

Transform Transitions

This visualization demonstrates smooth SVG transform transitions, where hovering over any square in a grid triggers an animated sequence that scales, rotates, and repositions it before fading it out. It uses D3 v3’s matrix decomposition to interpolate between arbitrary transform types, such as moving from a simple translate to a combined scale and rotate. The grid consists of 960 by 500 pixel area divided into 20-pixel cells, colored via HSL based on row and column position. Each cell listens for mouseover events, then chains transitions with delays to animate the transform and opacity changes.
