* Red Bar Width bug fix
In some cases, the widths of the red topic-term bars did not decrease (as they should have) from term \1 to
term \R under the relevance ranking with $\lambda = 1$. In other words, when $\lambda = 1$, there were topics
in which a narrow red bar was displayed above a wider red bar, which should never happen. The issue had to do
with the way topic-term bar widths are computed, and is discussed in detail in 32.
In the end, we implemented a quick fix in which we compute term frequencies implicitly, rather than using those
supplied in the createJSON() function. The upside is that the red bar widths are now explicitly controlled to
produce the correct visualization. The downside is that the blue bar widths do not necessarily match the
user-supplied term frequencies exactly -- in fact, the new version of LDAvis ignores the user-supplied term
frequencies entirely. In a few experiments, the differences are small, and decrease (as a proportion of the true
term frequencies) as the true term frequencies increase.
