The oversimplifications are so oversimplified, and so pretty. Miles is delighted.

At the end of the winding path through beautiful and mildly informative displays, there is a huge unmarked holomap of the wormhole nexus, surrounded by smaller displays that identify particular planets of interest - Beta Colony, of course, and Eta Ceta (with the other planets of the Cetagandan Empire lined up underneath), and Earth and Escobar and Tau Ceti. Barrayar isn't among the chosen few, but it is present on the larger map - Miles squints up at the detailed image to see if he can spot the Dendarii Mountains.
