The European River Map

Earlier this month Andrew Hill created a beautiful looking map of U.S. Rivers Colored by the Direction they Flow. Europeans now have their own river flow map.

Rivers of Europe is a CartoDB map showing only European rivers. The map uses the same color scheme as Andrews' US rivers map so I assume that the European map also colors each river by its direction of flow. If you click on the 'Datasets used in this map' you see the data used in the map. The data includes a column for 'bearing' so it is likely that that the rivers are colored by their direction of flow.
