Ask HN: What data visualization about Hacker News would you like to see?

I have been working for a while on a tool called HN EPLORER, which uses the HN API to acquire data from the website and then process it to do visualization and interactive searches.

Today I acquired all the data from 2017 and I will be soon blogging about it.

I was wondering what kind of charts/stats people would like to see.

Some examples are: - heatmaps showing what times most posts are posted - bars showing which days of the month are more active - word clouds showing most used terms in titles

I am looking for suggestions to expand the visualizations, so let me know if you have any ideas.
