A thousand randomly moving points drive a live Voronoi tessellation, visualized as colored cells on a Canvas. A separate SVG circle tracks the mouse, while the page displays the frame rates of the data updates, the tessellation computation, and the overall rendering. The heavy Voronoi calculation runs in a Web Worker using `d3.voronoi()`, keeping the mouse tracking responsive even when the tessellation lags behind.

AI-generated description

This block implements two independent processes:

one that computes the new values of data (by moving them randomly around)
one that asks a javascript worker to compute the voronoi tesselation of the data, and draws the polygons on callback

A SVG overlay tracks the mouse: it stays responsive even if the voronoi calculation is sluggish.

We watch the performance of both processes and display their fps rates. Tweak the data range and time intervals to see how they relate.

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.

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.

Voronoi Circles

Voronoi Circles uses D3’s Voronoi tessellation to partition a canvas into regions around moving points, with each region filled by a colored circle that pulses and shifts in size. The animation, rendered with the Canvas API, computes the Voronoi diagram via `d3.voronoi` and updates the drawing each frame. The example demonstrates how Delaunay-based spatial subdivision can drive a simple, rhythmic visual effect.

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.

Bounded Voronoi Tessellation

This interactive visualization demonstrates a bounded Voronoi tessellation, where 100 randomly placed sites partition the SVG canvas into colored polygonal cells. The mouse controls the first site, dynamically updating the diagram as it moves. The code uses d3.voronoi to compute the tessellation and d3.polygonHull to create a convex hull around the sites, which is then expanded outward to bound the diagram. Artificial points are added along this expanded hull to ensure the Voronoi cells are fully enclosed, with the generator sites rendered as circles and the convex hull traced as a pink line.

Canvas Voronoi

This example visualizes a Voronoi diagram of 100 randomly generated points, with the cell containing the mouse position highlighted in red. As the cursor moves, that site and its cell update in real time. The diagram is rendered entirely to a Canvas 2D context using the d3-voronoi API, computing both cell polygons and Delaunay links. The code draws all cells with black strokes, site markers as small circles, and semi-transparent link lines, demonstrating how d3-voronoi outputs geometric data suitable for immediate canvas drawing.

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.
