I have a data frame with rows of datetime elements (or perhaps they're text, I'm reading them in from a csv)Ex:.
2017-07-14 09:10:40

I'd like to graph how many rows there are per date, or per hour. (dates on x axis and number of rows on y axis).
How can I do that? I recognize that I'll need to do a count, but I don't know what to do with the number once I have it for each date. I guess I'll need to map it to a new df or something?
Thanks!
