Explore, analyse, modify, and learn from streams of data.

Streamtools is a new, open source project by The New York Times R&D Lab which provides a general purpose, graphical tool for dealing with streams of data.

It provides a vocabulary of operations that can be connected together to create live data processing systems without the need for programming or complicated infrastructure.

These systems are assembled using a visual interface that affords both immediate understanding and live manipulation of the system.

You can find the full docs here.

We also have a detailed overview of streamtools on the NYT R&D blog.
