I don't understand what value the prose provides over spending the same amount of effort producing clear, easy to read infographics.
Instead of producing awkward and difficult-to-read English sentences, why not use the same content generator to produce completely accurate and easier to read dynamic data visualizations?
If you do automated content well, it's not awkward and difficult to read ;)
As far as visuals vs prose, I see it as "both-and" rather than "either-or". And in addition to our journalism and personalization work, we also integrate with interactive visualization tools like Tableau.
