1. A computer program product comprising a non-transitory computer readable storage medium having computer readable program code embodied therewith for navigating a hierarchically structured document using iconic representations thereof displayed in a graphical user interface, said computer readable program code comprising:

  • computer readable program code configured to obtain access to a hierarchically structured document having a plurality of hierarchical levels;

    computer readable program code configured to, for each of said hierarchical levels, obtain a word list with a word count for each word included therein;

    computer readable program code configured to, for each of said hierarchical levels, create a tag cloud based on said words in a respective one of said hierarchical levels and said word counts thereof;

    computer readable program code configured to display, in said graphical user interface, a table of contents including a plurality of labels associated with respective ones of said hierarchical levels;

    computer readable program code configured to facilitate display of a first tag cloud of said tag clouds in association with a first hierarchical level upon detecting a selection of a corresponding one of said plurality of labels associated with said first hierarchical level, wherein said display said first tag cloud includes a nested icon representing a second tag cloud of said tag clouds corresponding to a second hierarchical level at a different hierarchical level of said hierarchically structured document than said first hierarchical level,wherein said table of contents and said tag clouds are associated to display in-context visualization of information about select levels of said hierarchical structure document;

    computer readable program code configured to obtain a selection of a given one of said words in said first tag cloud;

    computer readable program code configured to highlight, in response to said selection of said given one of said words, all entries in said table of contents for said hierarchically structured document containing at least one instance of said given one of said words;

    computer readable program code configured to receive a selection of said nested icon displayed in said first tag cloud; and

    computer readable program code configured to display said second tag cloud corresponding to said second hierarchical level of said hierarchically structured document upon detecting said selection of said nested icon, wherein said second tag cloud is displayed simultaneously with said first tag cloud.
