In this project, the client from a database of postal codes, wanted to visualize the distribution of their customers, we created a heat map for him with several options to be able to see the location of his clients, and how they are concentrated throughout Canada and other countries. We use geocoding technologies to discover the locations and assign coordinates to the records, in addition, the Google Maps API and some JavaScript to create this very useful tool for analysis.
