Rivers of the Philippines

The Philippines has one of the most intricate river networks in Southeast Asia, yet most maps reduce it to a handful of named waterways. This piece renders the full network — thousands of segments — using a minimalist dark palette that lets density do the storytelling.

Luzon’s northern highlands reveal themselves as a dense tangle of drainage lines feeding into the Central Plain. Mindanao’s scale becomes apparent. The Visayas, fragmented by sea, show each island as its own hydrological system.
