Plot a count of records during a date range

Plot a count of records during a date range

Hi all,

I am far from a SQL expert, but this feels doable and I just don't know how.  If I had a table that looked something like Stage History..
 Record Id
 Start Date
 End Date
 Stage
 Duration (Days)
 11111
 10/01/2020
 10/21/2020
 Needs Analysis
 20
 11112
 09/20/2020
 12/03/2020
 Needs Analysis
 74
 11113
 11/10/2020
 12/23/2020
 Need Analysis
 43

What I'd like to do is make a Line Chart where  
X Axis = Week of Year
Y Axis = Count of Records while in Needs Analysis
So each record would add to the line while between the Start and End dates. 

My thought is I'd need to create a query to create a row for every day it's in the duration?

Any one have any suggestions on how to accomplish this?

Thanks!
