Explains the formal definition using Euclidean distance, perpendicular bisectors, and half-plane intersections. Covers two production-grade algorithms: Fortune's sweep line (O(n log n), batch) and Bowyer-Watson (O(n log n), incremental). Includes benchmarks showing the naive approach is 1,200x slower than Fortune's algorithm at 10,000 sites. Demonstrates Python implementation using scipy.spatial.Voronoi (backed by Qhull), and surveys applications in robotics path planning, computer vision superpixels, computational biology, urban planning, game terrain generation, and network design. ## Full article daily.dev links to this article rather than hosting it.
