This example builds a Voronoi spanning tree on 1,500 random points using d3.voronoi, with SVG rendering. It visualizes short paths by hopping from each cell to its neighbor that is nearest to a moving root point, computed via a custom `diagram.find` function. As the mouse moves, the tree updates in real time, showing only the edges that link sites along efficient routes toward the cursor. The code leverages d3.v4’s voronoi layout and SVG line elements to display the redrawn spanning tree.

AI-generated description

Using <a href='http://bl.ocks.org/Fil/1b7ddbcd71454d685d1259781968aefc'>Voronoi.find(x,y)</a> to create a spanning tree.

The strategy is to hop from any site to the nearest site that is nearer to the designated root (compare to the <a href='http://bl.ocks.org/Fil/82d889261f3b980a932fb9f9ef299c40'>Voronoi spanning tree long path</a>).

Voronoi Spanning tree - short paths

The visualization draws a Voronoi spanning tree that connects 1,500 randomly placed sites by hopping from each site to a neighboring site closer to a moving root point. As the mouse moves, the tree’s edges recompute in real time, highlighting short paths toward the cursor. Built with D3 v4, it uses `d3.voronoi` to compute cells and edges, with a custom `diagram.find()` and `diagram.next()` method to traverse the diagram. The SVG rendering shows semi-transparent polygon boundaries and black spanning lines, with red highlighting on found cells.

Voronoi Spanning tree - long paths

This example visualizes a Voronoi spanning tree using a dataset of 1,500 randomly generated sites. A red line connects each site to its nearest neighbor in the direction of a user-controlled root point, which follows the mouse cursor. The resulting tree reveals long, winding paths as the connection logic prioritizes proximity to the root over local clustering. Built with d3.v4 and the d3.voronoi API, it renders SVG polygons for the diagram and lines for the spanning tree, updating dynamically on mouse movement.

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 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 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.

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.

Voronoï playground : Do you see the path ?

The example reveals emergent path-like structures within a Voronoï tesselation by generating cells whose borders align along a user-drawn route. Viewers click and drag to create a continuous white stroke, and the visualization dynamically seeds limited-distance Voronoi cells around that path, coloring and styling each cell border to suggest a coherent corridor. Built with D3 v4, it uses `d3.drag`, `d3.line`, and a custom `d3.distanceLimitedVoronoi` plugin to recompute cells in real time, with an SVG filter applied for visual saturation.

svg voroni spiral

This example shows a static Voronoi tessellation over a set of random points, with animated spiraling lines tracing each polygon’s edges in sequence. It uses D3’s `d3.geom.voronoi` to compute the polygons from 40 random vertices, clipping them to the SVG canvas, and renders them as SVG `<path>` elements. The animation repeatedly shifts a point along each polygon’s perimeter, drawing a new line segment between consecutive points using `setInterval` and updating the `d` attribute of appended paths. The code relies on D3 3.5.5 and custom helper libraries (`d3-jetpack` and `d3-starterkit`) for concise SVG manipulation, with the overall rendering purely vector-based in SVG.
