Bins! An easy path to make them using Fast API, PostGIS and JavaScript
Vinícius Cruvinel Rêgo

In order to manage and analyze geospatial data, more frequently are being used the Binning Process to achieve consistent results. In a more generic way, Binning is the process to group (cluster) points data into defined geometric features like squares or hexagons. For example, the process that uses hexagon polygons is defined as "Hexagon Binning". Nowadays, this process became more used as provides a quick and efficient way to summarize (clustering) points data, giving a better overview principal when the amount of points are high.
