Hi, I got the following graph for each job title with salary in box plot:

1668177465867
1668177465867902×50 3.09 KB

1668174931442
16681749314421158×835 36.9 KB

so there are some outliers here, presented as dot, I want to make some jitters like this for each job title have outliers:
1668177677876
1668177677876403×556 22.6 KB

Is there any way I can do it with Vegalite package?
also there are some job title have empty value which is strange(eg.ETL developer), can someone also gives me some advice how to remove them please(using inmemorydataset package)?
Thanks in advance!
