Professional Diagram

The Voronoi Diagram

In mathematics, a Voronoi diagram Wiki Logo is a partitioning of a plane into regions based on distance to points in a specific subset of the plane.

The IDW Diagram

Inverse Distance Weighting (IDW) Wiki Logo is a type of deterministic method for multivariate interpolation with a known scattered set of points.

g0v Air Pollution Map

The g0v Realtime Air Pollution Map was developed by g0v.tw open government. This site presents the geo-location and PM2.5 real-time data of all the PM2.5 stations.
