  Modern particle physics experiments usually rely on highly complex and
large-scale spectrometer devices. In high energy physics experiments,
visualization helps detector design, data quality monitoring, offline data
processing, and has great potential for improving physics analysis. In addition
to the traditional physics data analysis based on statistical methods,
visualization provides unique intuitive advantages in searching for rare signal
events and reducing background noises. By applying the event display tool to
several physics analyses in the BESIII experiment, we demonstrate that
visualization can benefit potential physics discovery and improve the signal
significance. With the development of modern visualization techniques, it is
expected to play a more important role in future data processing and physics
analysis of particle physics experiments.
