How to make a timeline in google Sheet

I've a several task series like this on several day in Google sheet

|Task 1     |03/08/2021 03:00:03    |03/08/2021 03:10:05||Task 2     |03/08/2021 05:00:03    |03/08/2021 05:21:37||Task 3     |03/08/2021 11:20:03    |03/08/2021 11:34:42||Task 4     |03/08/2021 06:20:01    |03/08/2021 07:43:12||Task 5     |03/08/2021 03:30:02    |03/08/2021 04:09:10|

I would like to make a timeline like this picture below in Google Sheet.It was easier to make a timeline with a Json than Google sheet.

May be I could insert the code in Gsheet but I don't know how to.
