Level Four (L4) is a free and open source visual analytics platform. The goal is to provide a comprehensive and integrated toolset to transform raw data into visual scenarios and stories.
The project is based on three components:
L4TK : data visualization toolkit
Models: data structures Methods: filters and manipulation of data structures Views: visual representation of data structures Controls: interactivity Presentation: publishing analytical results as stills, animations, and interactive mediums L4AE : visual analysis environment
A node-based procedural modeling system for designing a data visualization pipeline A scenegraph-based management system for controlling the visual variables of data objects A rendering system for the exploration of data worlds An animation and event management system for creating interactive scenes and story representations L4G : a common grammar and design pattern approach for creating complex recipes
A standard approach to describe representations influenced by Leland Wilkinson's The Grammar of Graphics A design pattern approach for "plug-ins" to evolve the platform A provenance approach for sharing analytical pipelines for collaboration Want to contribute? Get involved - write us!
Ohloh computes statistics on FOSS projects by examining source code and commit history in source code management systems. This project has code locations but that location contains no recognizable source code for Ohloh to analyze.
