"# Visualization of Geometries\n",

"With ROOT you can visualize complex geometries, for example the ones of the LHC experiments or the one of a space station.\n",
"In this notebook we will read a geometry from a ROOT file and display it. The possibility to save and resume geometries persisted on disk is a powerful feature as it avoids all the complex calculations behind the construction of a geometry from scratch, e.g. from a CAD or XML file."
