This map by Google is an amazing visualization of flows of small weapons over 18 years. The map utilizes animated lines to visualize the connection between importer with exporter. Direction of movement is indicated by the colour of the line, and shaded according to the type of arms being traded. Linked countries are shaded a lighter grey to distinguish them from others. A graph on the side shows the breakdown of imports and exports, and a time slider allows the user to choose a year. This tool combines extreme amounts of data (over 1 million data points) with the amazing rendering power of HTML5, displaying 3D interactive map with animations.
