For this challenge and lesson, we learned how to build maps for websites using Leaflet, d3, JavaScript and web scraping. The map is interactive where you can see the following:
All major earthquakes over a 4.5 magnitude
Tectonic plates
The challenge required the addition of a third version of the map, the major earthquakes, and the tectonic plates. These additions were relatively easy as it was just a copy and refactoring the code.
