Four thousand random points are colored by size, with the largest ten percent becoming Voronoi sites. The animation cycles through stages: it sorts points by size, uses the top ten percent as sites for d3.voronoi, then assigns every point the color of its site’s cell via the customized `diagram.find()` method. Points and cells fade, recolor, and reset every nine seconds using d3.interval and transitions.

AI-generated description

Group data points around the largest points.

The recipe is as follows:

sort data points according to their sizes (here size = d[3])
use top 10% points as Voronoi sites
bin all data points according to their Voronoi cell, using <a href='http://bl.ocks.org/Fil/1b7ddbcd71454d685d1259781968aefc'>voronoi.find()</a>. The binning is rendered by using the Voronoi sites's color.

Voronoi binning

4000 random points are colored by the nearest of 400 weighted sites, selected as the top 10% by a random weight and arranged as a Voronoi diagram using d3.voronoi. A custom `find` method on the diagram, which walks neighboring cells via halfedges and optimizes from the last result, assigns each point the site color of its containing cell. Circles are rendered in SVG, with radius proportional to the square of each point’s weight.

Rotating Voronoi in d3v4

A rotating Voronoi diagram animates dozens of moving points whose cells constantly morph, producing intricate curved patterns against a black background. The animation derives from points arranged on circular paths that rotate at varying speeds and radii, while the Voronoi tessellation updates each frame. The code uses d3.voronoi to compute the polygons and d3.line with the curveBasisClosed interpolator to render them. A custom resample function subdivides each polygon edge into three segments before drawing, creating the smooth, curved cell boundaries. The animation runs continuously via d3.timer, with points’ positions updated directly in response to elapsed time.

Rotating Voronoi in colors

Dozens of colored points orbit along concentric circular paths, while the Voronoi cells surrounding them are resampled and smoothed into curved, lens-like shapes that continuously rotate and morph. The animation is rendered as an SVG, with each cell’s fill and stroke sampled from a two-color linear scale. The code uses d3.geom.voronoi to compute cells, a basis-closed line interpolator for curvature, and d3.timer to drive the point motion and redraw the paths.

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.

Voronoi Tessellation

This interactive Voronoi diagram shows how a set of one hundred random points partitions a 960-by-500 SVG canvas into polygonal cells. Moving the mouse repositions the first site, causing the diagram to recompute dynamically with the red polygon, black links, and white site markers updating in real time. Built with D3 v4 and the d3-voronoi library, the example renders polygons as SVG paths, links as lines, and sites as circles, with all geometry recalculated on each mouse move.

Voronoi colorized spanning tree

A Voronoi diagram of 1000 random sites is colored by a spanning tree that connects each site to its nearest neighbor closer to a moving root point. As the mouse moves, the root updates, the tree edges redraw, and every cell's fill derives from the tree's branch angles and depth. The example uses d3.v4 with `d3.voronoi` to compute cells and custom `diagram.find` and `diagram.next` methods for tree construction, then renders SVG polygons and lines with HSL colors.

Voronoi Edges

This example animates the edges of a Voronoi diagram generated from 1,500 normally distributed random points. The visualization uses d3.Delaunay and d3.voronoi to compute the diagram, then renders its line segments incrementally on a Canvas using a JavaScript generator and requestAnimationFrame. Each frame draws approximately five new edges with random colors from d3.hsl, creating a dynamic, colorful buildup of the geometric structure.

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`.
