VisBOL is a web-based visualization
tool used to depict genetic
circuit designs. This tool depicts simple DNA circuits adequately,
but it has become increasingly outdated as new versions of SBOL Visual
were released. This paper introduces VisBOL2, a heavily redesigned
version of VisBOL that makes a number of improvements to the original
VisBOL, including proper functional interaction rendering, dynamic
viewing, a more maintainable code base, and modularity that facilitates
compatibility with other software tools. This modularity is demonstrated
by incorporating VisBOL2 into a sequence visualization plugin for
SynBioHub.
