Abstract
In this paper, we aim to extend our work in VAST Challenge [7] of IEEE visualization conference last year, where we use visual analytics to solve an environment problem on why a local attractive bird, Rose-Crested Blue Pipit, is decreasing. Given the large scale and multi-dimensional datasets on chemical releases, we develop immersive visual analytics to find the connections between manufactures and sensor readings, and eventually, to discover the potential reason of the bird decreasing.
