Interactive 3D visualization of the distribution of nearby voids (use interactivity at https://irfu.cea.fr/Projets/COAST/cavity-CF3.html). The positions of the CAVITY survey target galaxies are given by markers colored according to their void membership as indicated in the column displayed on the right-hand side. In the online version, hovering over the galaxy markers reveals the galaxy positions, identifiers, and void memberships. The wireframe polygon is a high-density (δ_m = 1.3) isosurface of the reconstructed CosmicFlows-3 overdensity field. Also in the interactive version, the user can rotate, pan, and zoom in and out using the mouse. Single-click or double-click on the elements listed on the right-hand side column hides them or singles them out from the scene.
