Choropleth of Fertilizer Exports (USA)

This visualization is inspired from here.

Interactivity

  • This choropleth represents the exports data from year 2010.
  • By keeping mouse pointer on particular country for a while, the exact volume of exports is displayed from 1990 through 2012 so that we can compare them with the export volume of the year 2010.
  • Zoom-in functionality is implemented using mouse click. Again a mouse click triggers zoom-out when the map is already in zoomed-in mode.
