Hi, I am looking to create a scatter plot of a time series object with date on the x-axis and frequency count on y.

```
    df['Date'] 

   2019-09-30
   2019-12-31
   2019-12-31
   2020-03-31
   2020-12-31
   2020-06-30
   2020-09-30
   2020-12-31
   2020-12-31
   2020-12-31
   2021-03-31
   2021-03-31

```

My question is how do I do this in plotly and dash. A scatter plot with date in x-axis and aggregation values in y-axis. Do plotly graph objects support aggregation?

```
Desired output:
2019-09-30 1
2019-12-31 2
2020-03-31 1
2020-12-31 4
2020-06-30 1
2020-09-30 1
2021-03-31 2
```

Looking at the examples on [https://plot.ly/javascript/aggregations/](https://plot.ly/javascript/aggregations/) is a good place to start.
