alien nation. (data visualization)

The following is a data visualization of over 18,000 UFO sightings. To accomplish this visualization, I structured and processed a dataset containing the number of reported sightings, along with their duration and location. Once the data was properly structured, I ran it through a custom program in Processing, which placed circular markers on a map based upon longitudinal and latitudinal values.
The green set of dots represent the location each sighting and the vertical white dots represent the frequency and duration of each sighting.
