TripHappy, a trip planning startup created an interesting map that visualizes all travel itineraries made by its users in the past two years (over 17,000 itineraries in 184 countries). The map was created using just the travel points, without any land, sea or geographic borders.
The main visuals were made using Gephi, a free and open-source software for data visualization. The countries have been color-coded based on the popularity of a given connection (all countries of the same color have trips that go between each other more often than other countries).
The overall effect is really interesting but it starts to be even more surprising once you look at the high-res version of the map. You will notice that each and every dot has a city label, which is not particularly useful but it let you discover more details of the dataset.
The overall user experience is far from being perfect and the cartographic aspects of the project have many shortcomings but it’s still a lot of fun trying to guess the countries and airports as well as discover travel inequalities around the world.
