When a gene list of interest is obtained from an experiment in our daily research, we'd like to find out if some of these genes belong to a certain gene group attributed with special functions or features. Venn diagram is a widely used visualization of all possible logical relations between a finite collection of different sets. Taken experimental gene list and ecDNA genes as two sets, finding ecDNA genes out from the experimental gene list is like to resolve the problem of set relationships.

Therefore, venn analysis is offered for easy discovery of ecDNA genes in the gene list of your interest. With this tool, finding out ecDNA genes for biological inference, further experimental study, or downstream bioinformatics analysis is convenient and efficient.
