The solution should reflect the solution used for the radial tree diagram, e.g.

(.append "tspan")
(.attr "class" "sense-paragraph")
(.attr "dy" "4px")
(.text (fn [d]
         (when (<= (+ (count (.-name (.-data d)))
                      (count (.-sub (.-data d))))
                   16)
           (.-sub (.-data d)))))
