  The Taishan Antineutrino Observatory (TAO or JUNO-TAO) is a satellite
experiment of Jiangmen Underground Neutrino Observatory (JUNO) and located near
the Taishan nuclear power plant (NPP). TAO will measure the energy spectrum of
reactor antineutrinos with unprecedented precision, which will benefit both
reactor neutrino physics and the nuclear database. A detector geometry and
event visualization system has been developed for TAO. The software is based on
ROOT packages and embedded in the TAO offline software framework. It provides
an intuitive tool to visualize the detector geometry, tune the reconstruction
algorithm, understand the neutrino physics, and monitor the operation of
reactors at NPP. The further applications of the visualization system in the
experimental operation of TAO and its future development are also discussed.
