In detail, I would like to integrate, in the same plot. For visualization, at one point we filter for all nodes with less than 2 edges. The layout sets the basic parameters of the graph, such as radius. The example command will get each line where the feature (3rd column) is a CDS, that has the “acrA” (in the complete line) pattern to write the “circos labels file” using the ID attributes column as label (string as found in the gff), giving these features a “red” color option.
