I have a set of data in the following format: hour (HH); latitude1; longitude1; latitude2; longitude2; value Latitude1 - Longitude1 is the start location Latitude2 - Longitude2 is the end location I want to draw lines between those locations and the thick of the line depends on the value. Each hour there is a different set of points with these characteristics and if there is an animation there would be some extra money in it (Something like http://www.aaronkoblin.com/work/flightpatterns/). The tool to use must be Processing (processing.org) Thanks, Keywords: Data, Processing
