ClustrMaps is a website that provides a simple and visually appealing way to display visitor locations on a world map. Its primary function is to create interactive heatmaps that show the geographical distribution of website traffic. This allows website owners to see where their visitors are located, gaining insights into their audience's demographics and geographic reach.

The map displays visitors as clusters of points, with larger clusters indicating higher concentrations of visitors from that area. The density of these clusters visually represents the volume of traffic originating from specific regions. The color intensity of the clusters typically increases with the number of visitors from that location.
