This interactive 4D visualization has been produced as part of the following research paper: “Cosmicflows-3: Cosmography of the Local Void” by R. Brent Tully, Daniel Pomarède, Romain Graziani, Hélène M. Courtois, Yehuda Hoffman, and Edward J. Shaya, The Astrophysical Journal 880 (2019) 24 https://doi.org/10.3847/1538-4357/ab2597 Preprint: https://arxiv.org/abs/1905.08329 IfA Press Release: http://www.ifa.hawaii.edu/info/press-releases/local_void/

This is the interactive version of the Figure 3 of the article, where orbits of galaxies, groups of galaxies, and clusters of galaxies, derived from the Numerical Action Method, are superimposed on the Local Void iso-density contours. The signpost anchored at the present Milky Way location has 5,000 km/s-long arrows pointing to the SGX (red), SGY (green), SGZ (blue) directions of the Supergalactic Coordinate System.

A video visualization has also been produced as part of this publication and is available here: https://vimeo.com/326346346
