About

deck.gl is a WebGL-powered framework for visual exploratory data analysis of large datasets. The basic idea of using deck.gl is to render a stack of visual overlays, usually (but not always) over maps.

To make this simple concept work, it handles a number of challenges:

  • Large data sets and performant updates
  • Interactive event handling such as picking
  • Cartographic projections and integration with underlying map
  • A catalog of proven, well-tested layers
  • Easy to create new layers or customize existing layers

deck.gl has been designed according to the principles of the Reactive Programming Model, inspired by .

The key to writing good, performant deck.gl applications and layers lies in understanding how to minimize updates and redundant calculations.
