The Prism trend script is a tool for quickly visualizing flow data as a time-series broken down into several configurable bins by SiLK's rwfilter tool. The script can be used directly, or might be used as a component in other more specialized scripts.

In addition to providing immediate visualizations, the Prism trend script can store these breakdowns in a relational database (currently supporting PostgreSQL or sqlite) for later quick lookup.

Prism 1.1 requires netsa-python 1.3, Rayon 1.3.0, and SiLK 2.0.0 or better.
