The Charm City Circleator–or Circleator for short–is a Perl-based visualization tool developed at the Institute for Genome Sciences in the University of Maryland’s School of Medicine. Circleator produces circular plots of genome-associated data, like this one:
Common uses of the tool include:
- Displaying the sequence and/or genes in a GenBank flat file.
- Highlighting differences and/or similarities in gene content between related organisms.
- Comparing SNPs and indels between closely-related strains or serovars.
- Comparing gene expression values across multiple samples or timepoints.
- Visualizing coverage plots of RNA-Seq read alignments.
This product includes color specifications and designs developed by Cynthia Brewer (http://colorbrewer.org).
