Graph and sequence of action

Hi all, 

Here is the business problem that I am trying to find the proper graph (if available) to. 

I have customers who make actions within a year.   There is no direct link between the actions (they are independent) but they are sorted in order (earlier to latest). 

I need to create a graph that would show the movement of my customers between actions. 

Data would look like this. 

Year               Customer        Sequence_of_Action     Action

2019                   123                             1                      A

2019                   123                             2                      C

2019                   123                             3                       A

2019                    456                            1                       B

2019                    456                            2                        C

...

The actions are always  ordered by year and in sequence for each customer.  There is no missed steps. 

I am looking to see something like this...

Any suggestion are appreciated. 

Thank you all

Francois
