Existing tools of text analysis and network visualization such as Voyant <ref xmlns="http://www.tei-c.org/ns/1.0" target="ftn1" n="1" /> or Gephi <ref xmlns="http://www.tei-c.org/ns/1.0" target="ftn2" n="2" /> are either missing modules for character network analysis or require preliminary steps on data preprocessing from the user and therefore are not easy-to-use for some humanities scholars who lack programming skills. Interactive tools in addition often lack features to ensure reproducibility of results.
