So...a single client is sharing their preference with you, and you're wondering of that's a global phenomenon?

You're going to have to define "visualization" in this context for me to give you a specific answer.

In general, however, individual customers have individual preferences. You might get a lot of value from looking at a behavioral profiling tool like DISC or Myers-Briggs. A C in the DISC profile is going to love tables...an I is probably going to immediately be bored with them.

One good thing you did is find out the preferences of how this client wants to be communicated with. Keep doing this, up front, at the beginning of every project. Ideally during the sales process--this will show you how to sell to them! Since most salespeople are running the same old dusty presentation, which was made to sell to only ONE of those types, they're cutting out 3/4 of their market! If they'd find out the preferences of this prospect they're talking to now, they could easily personalize the info to sell to that prospect...and stand out past any competitors.

And the information is there, free for the asking.
