One day, you have a data. It looks like this.
So you want to turn it from this to this.
So you decided to add a column called count, and add 1 for each row.
Then you plot it out.
Geez... Okay that's obvious. Just plot every 1 out isn't help. That's why aggregation comes to the rescue!
So we try to create time bucket for 5 minute, then we group the time nearest to the bucket value.
Then we try to count objects inside each of the bucket
Our data becomes like this.
Then we can plot it out nicely!
