Layouts

Circular


Circular layouts are mainly used (1) if the displayed sequence itself is circular, (2) to display a non-circular sequence in a space-saving way, and (3) to show interactions between different parts of the sequence(s) using a chord diagram.







Linear




Linear layouts are more intuitive and easy to read, but may be extremely long and require zooming and panning.






Space Filling


The space-filling curve is more space efficient than a circular layout and are often used to display a global overview of the genome while maintaining the spatial distribution of features. However, space-filling curves can only show one feature set, and it's hard to visually estimate the distances between two positions in a sequence.






Spatial




Spatial layouts display sequences in a 3-dimensional structure.
