This article delivers the dynamical cosmography of the Local Universe withinz=0.1 (1 giga light-years). We exploit the gravitational velocity fieldcomputed using the CosmicFlows-4 catalog of galaxy distances to delineatesuperclusters as watersheds, publishing for the first time their size, shape,main streams of matter and the location of their central attractor. Laniakea,our home supercluster's size is confirmed to be 2 $\times 10^6$ (Mpc$h^{-1}$)$^3$. Five more known superclusters are now dynamically defined in thesame way: Apus, Hercules, Lepus, Perseus-Pisces and Shapley. Also, the centralrepellers of the Bootes and Sculptor voids are found and the Dipole and ColdSpot repellers now appear as a single gigantic entity. Interestingly theobserved superclusters are an order of magnitude larger than the theoreticalones predicted by cosmological $\Lambda$CDM simulations.
