LATtice is a free visualization program designed for exploring and comparing texts across a body of work. LATtice is structured to allow users to analyze texts from both the macro and the micro levels by creating summative visualizations but also allowing users to "'drill down' to the level of individual LATs to ask exactly what rhetorical categories make texts similar or different". LATtice also allows users to create multiple visualizations in tandem, thereby facilitating comparative perspectives on the same data set (often revealing different details).
