Where can I find charts with the amount of treasuries in existence? Is there a place where I can see a chart with the amount of treasuries in existence organized by treasury type?

Ideally it would be a resource that has multiple charts (for bills, notes, bonds etc...)

I cannot find anything on the fred.stlouisfed.org site
SIFMA: US Marketable Treasury Issuance, Outstanding, and Interest Rates

The hint here is that repurchases are relatively rare and prepayments are not an option so gross issuance that hasn’t yet matured is a decent proxy for outstanding amounts.
