COVID-19 triggered by SARS-CoV-2 has become a common problem faced by people all over the world. With the development of bioinformatics and the breakthrough progress of gene technologies. It is a challenging topic to use genomic datasets for SARS-CoV-2 research. In this paper, a 3D visualization method is pro-posed to show the A9 module of the metagenomic analysis system MAS. Seven coronaviruses of genera were illustrated and briefly analyzed. Comparing the visualization results, various SARS-CoV-2 genomes were represented as 2D and 3D maps under different conditions. Through related specific projections, the characteristics of the coronavirus can be observed intuitively from the projection results to provide an effective viewpoint for studying viral genomes.
