Good iterations, but why is Obama in the network visualization not connected to Trump? what does connection mean in this context? Are you showing handle co-occurence? if so, you should clarify, and maybe your network visualization should be included as well because it tackles a different problem

Also, did you try the matrix visualization?

why didn't you include the actual prototype here? why just an image? You need better labeling so users can understand it more easily

What insights do you plan to get from this?

Again, why just an image? :( what did you use to build this chart? You need better title, axis labeling etc. What is the insight from this? Why is trump tweeting before 1900?

It is going to be hard to find something insightful with this idea. Maybe if you annotate it with time events, e.g. when did the pandemic start

The treemap will be problematic for comparing time... maybe consider using something simpler first like a normalized stacked barchart of the top 20 mentioned accounts (color) over time (x). Y would be the % number of mentions

I like your idea of asking for what clusters would appear, but why would they be insightful? They really aren't connected to your tasks, so maybe you need a task that address that. Those clusters could be interesting, in the sense that they would be people that get mentioned together

Contents doesn't work...
