map of the world by mashing up airport data and the exact midpoint between any two airports
Mo Data stashed this in Data Visualizations
"Davies has created a new map of the world by mashing up airport data and a spherical Voroni diagram that creates new borders by finding the exact midpoint between any two airports. Borders set by treaties, rivers, and mountains are replaced with new lines driven purely by math. The result is a view of the world that looks more like a cellular diagram or mosaic than a map."
If you're a data scientist and are looking at travel data, this might be an interesting approach to follow.
