What is Datm?

Datm is a graph-based, in-browser, data manipulation and visualization application. It’s written in Python and uses the django web framework. It allows the user to:

• Create “projects” and add datasets to them (see add-datasets demo).
• Transform datasets using “manipulation sets” (similar to dplyr, see transform-datasets-ms demo).
• Transform datasets using SQL (see transform-datasets-sql demo).
• Join two datasets (see join-datasets demo).
• Generate Python source code for transformed datasets (see generate-source demo).
• Access datasets easily from Python.
• Visualize datasets (see dataset-visualization demo).

See the Tutorial for an overview of Datm’s features.
