Nice work up and a fair amount of work..thanks for putting this together. I was a market-logistics-data analyst prior to retiring. Much of my work involved modeling global logistics networks. I've not heard of Flourish, though I've been out of that business for a while now. I used Tableau for most of my visualizations. Modeling was done in software that is a world apart from Tableau/Flourish.
In any event, I like the plots..very interesting and nicely done. I would typically use plots like this to get a feel of what the data was saying and to emphasize specific points in a presentation(the sunburst diagram on market segmentation is nice). My audience (consumers of my work) was generally upper management and C-level folks. While a few (very few) were data-oriented, in general they had little patience for digging into lots of plots to answer questions..that's what they had me for. Often I would prepare one or more user-driven dashboards that was easy to filter down and answer (their) questions. I'd have a graphical workup with a half dozen filters (on/off, sliding scale..etc..) that would quickly narrow things down without them having to think too hard..questions are easy, answers actually require work.
With a couple filters clicked, one could answer a (completely arbitrary, I ride primarily road and mountain bikes) question like, "I want a triple crank, Tiagra components or above, rim brakes, and it has to fit 50mm tires..what bikes should I look at?" Four on/off filters would result in a list of Mfgs and models, along with price..etc..
fwiw..Tableau has "Tableau Public" software that anyone can use free..here's a gallery of all kinds of dashboards:

Great work..if I were in the market for a new hybrid, this would be a gold mine of info..
