This example demonstrates how Voronoi diagrams improve hover interaction on a scatterplot by partitioning the chart area into cells around 50 randomly generated points. Clicking the chart reveals the Voronoi overlay, while moving the mouse highlights the nearest data point with a colored ring and displays its properties in a text output. The implementation uses D3 v4’s `d3.voronoi` layout with the `find()` method to locate the closest site, alongside `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` for scales and axes. Points and axes are rendered as SVG elements within an HTML page.

smushed-voronoi

Three charts show how weighted Voronoi diagrams change pointer hitboxes for scatterplots. Each chart’s Voronoi cells, colored by series, respond to a slider that adjusts the X-to-Y distance ratio between 1 and 100. The code uses `d3.voronoi()` to compute cells, `d3.drag()` for moving points, and a custom `calcXY` function to weight dimensions. The interaction updates cell geometry and highlights the nearest point to the cursor in real time.

Scatterplot with Voronoi

This interactive scatterplot uses a Voronoi partition to link each data point to its nearest region, improving tooltip responsiveness in dense areas. The visualization plots life expectancy against GDP per capita using World Bank country data, with points colored by region. However, the Voronoi cells cover the entire chart, so the author adds a distance check in the `mousemoved` function to only display tooltips when the cursor is close enough to the actual data point, preventing confusion in sparse corners. The build uses the D3.js v3 library with SVG rendering and a subtle animation.

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 Labels

This visualization demonstrates a heuristic for labeling scatterplots using Voronoi tessellation. A set of 200 normally distributed points is rendered as small circles, with each point's Voronoi cell drawn as a gray polygon. A orange line connects each point to its cell’s centroid. The code only labels points whose cell area exceeds a threshold (2000), placing the index number at the point’s position. The label’s orientation—top, right, bottom, or left—is determined by the angle between the point and its cell’s centroid, computed using `Math.atan2`. Implemented with D3 v3, it uses `d3.geom.voronoi` with `clipExtent` and `d3.geom.polygon` to generate and analyze cells.

Voronoi Labels in d3v4

This example uses a Voronoi tessellation to place labels in a scatterplot, showing how cell area and centroid direction determine which points get labeled and where. The code generates 200 random points, computes their Voronoi polygons with d3.voronoi, and filters for cells larger than 2000 square pixels. For each qualifying point, it compares the centroid to the point itself, choosing a label orientation among top, right, bottom, or left based on the angle. The visualization renders SVG paths for cell borders and centroid lines, with labels positioned via text anchors and offsets.

Voronoi Test (N=2)

The example shows a Voronoi diagram computed from two fixed points, with each cell and its corresponding point circle filled using the same color from `d3.scale.category10()`. Using d3.v3 and SVG, the code applies `d3.geom.voronoi` to generate the cell polygons, then renders them as `path` elements with a hover effect that increases fill opacity. The circles are positioned via `transform` translations, and both layers receive black strokes from the shared CSS rule.

Voronoi-based point picker

This example demonstrates a Voronoi-based point picker that lets users hover over the clipped Voronoi cell around each point to highlight both the cell and the corresponding circle. Using D3.js with the `d3.geom.voronoi` API, the code generates 100 random vertices and computes their Voronoi diagram, then clips each cell with `clipPath` elements. Mouseover and mouseout events toggle the fill color of the path and the point circle from light gray to blue. The underlying data is purely synthetic, created via `Math.random()`.

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.
