Color Mesh

Color Mesh II

This example displays a colorful abstract image made of triangular cells formed by a Delaunay triangulation of a Poisson-disc sample of points. The visualization is rendered as SVG paths in a browser using the D3 v3 library, specifically calling `d3.geom.voronoi` to compute the triangulation. Each triangle is filled and stroked with a color determined by the `d3.lab` color space, which maps the centroid’s distance from the center to a luminance and hue gradient, creating smooth color transitions across the canvas. The underlying point distribution is generated via a custom Poisson-disc sampler, ensuring evenly spaced vertices.

Colorcomb II

A Voronoi diagram of hundreds of colored cells animates on a black canvas, with each cell’s color shifting over time toward a shared palette. The visualization is rendered using the `d3-voronoi` library, which computes the tessellation, while a Canvas drawing loop continuously updates the cell fills. The animation derives from per-cell color interpolation, creating a slowly morphing mosaic of polygons. The code is a single self-contained HTML file using JavaScript and the Canvas API, with no external data source beyond the procedurally generated initial cell positions and colors.

Poisson-Disc IV

This example generates a set of points using a Poisson-disc sampling algorithm and renders them as a clipped Voronoi diagram. The SVG paths are filled with a color mapped from each polygon’s area using a cubehelix color scale, creating a smooth gradient across the canvas. The code uses d3.geom.voronoi for the diagram, d3.scale.cubehelix for coloring, and d3.svg for rendering. The Poisson-disc sampler is based on Jason Davies’ implementation, with a fixed radius of 5.68 pixels.

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.

Voronoi Tesselation

This example visualizes a Voronoi tessellation of 100 random points within an SVG canvas, with each cell filled by a random HSL color and vertices marked as small circles. Moving the mouse repositions the first vertex, dynamically recomputing the tessellation and updating only the paths whose geometry changed. The code uses the D3 library’s `voronoi` function from the `jit/voronoi.min.js` module, along with SVG path elements and `d3.svg.mouse` for mouse coordinates. The rendering is immediate, without animations or transitions.

Colorcomb

Four hundred particles drift and bounce across a full-screen canvas, their paths perturbed by random forces and velocity damping. A Voronoi tessellation of their positions is drawn twice: first as a thick black stroke for contrast, then each cell is stroked with a color derived from its centroid’s screen coordinates, converted through `d3.lab` and `d3.hcl` with a hue that rotates over time. The animation uses `d3-timer`, `d3-voronoi`, and Canvas 2D rendering.

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.

Voroni & Chromatic Scale

This visualization displays a Voronoi tessellation of 2,000 random points, with each polygon’s fill color mapped through a chromatic scale. The example uses D3 v4.0 with the `d3.voronoi` layout, `d3-scale-chromatic`’s `d3.interpolateRdYlBu` for continuous ColorBrewer coloring, and SVG paths for rendering. On mouseover, all polygon fills recolor based on the Euclidean distance from the hovered point’s coordinates, creating an interactive distance-based heatmap effect.
