Allen Brain Atlas-Driven Visualizations (ABADV) is a web-based application created for visualizing expression energy data from the Allen Brain Atlas. ABADV combines the ABA Application Programming Interface (API), a resource enabling programmatic access to their dataset, with Data-Driven Documents (D3), a library that uses digital data to drive the creation and control of dynamic and interactive visualizations. This allows users to quickly and intutiively survey expression energy data across multiple brain regions.
