Design of an interactive map that is built in real time using data downloaded from (WQP)

Several open source JavaScript Libraries intervene in that process. In particular, I used d3.js, a powerful library that is perfectly suited for combining visualization components and data-driven approach. Voronoi diagrams are part of that library. To handle the text files, alasql.js
("à la" SQL) provides a very convenient way to sort and perform queries on large data files using the Structured Query Language (SQL).
