Table 3. Methods used to extract elements of the full data XML files, and where the results are visualized in this manuscript.

In Figure 2, on the left, the table of contents is generated by the method divNav(). The method htmlSingleSection() instead prints one single section’s content as a customized html paragraph of our platform. We use the methods refInSingleLine() and actsInSingleLine() for picking out which nodes (sections) should be linked together with an edge in Figures 2 and 12.

Element	Figures	Method

Single Section ( HC)	Fig. 2, Fig. 11	htmlSingleSection()
Inbound Complexity Graph, JSON file	Fig. 2	refInSingleLine()
Outbound Complexity Graph, JSON file	Fig. 12	actsInSingleLine()
