I liked the four visual components. The treemap and the bubble chart visualization seem redundant, though. I think it would be better if they showed different but complementary information. The second one, e.g., could show the number of most- cited authors (above a threshold) per topic. They could also be linked to one another (i.e., interactions in one would be reproduced in the another).

The network visualization could be improved by considering paper metadata. One example would be to color nodes according to the paper publication year, a feature that would help users to find time intervals of interest. Please see [1].

I should notice that such recommendations would be limited by the volume and accuracy of the survey data included by the survey authors, i.e., if the authors only categorize 50–100 papers for a topic/field with thousands of papers, the recommendation might be sound with respect to the list/set of categories, but eventually useless (as such work could already exist outside of the set of collected papers). Perhaps, additional factors such as number of papers on a particular category over time (or over the course of the last N years), citation counts (if available), centralities (incl. PageRank, for instance) in the citation and/or co-authorship networks, and so on, could be eventually added to this recommendation approach.
