Circos are a tecnology company that have redefined how we think about visualising genomic data. They’ve pioneered the use of circular graphs to map genomes and chromosomes, which allows for a much more intuitive and visually efficient way to compare genomes. They have lots of documentation on their website about how to set up their software to create genome maps. Some of this is tutorials and some of it is lectures. One of the first lectures they have is about design principles and data visualisation, and it’s well worth a read for anyone who has to represent data of any type.The presentation focuses on applying graphic design principles such as simplification and consistency to graphs and charts. It shows how minimising unnecessary or redundant visual elements makes your graphs much easier to read and your data much easier to interpret. Take a look at the link below.
