Wisconsin does not release early vote totals so I dont know where this info came from.
It says NBC News
Are you sure?
It has a link to NBC, which does show the same:

The footnote in the data says it was compiled by TargetSmart. They apparently can translate raw voting data to party affiliation by addresses or other info,
This election is the first I heard of them.
Could it be just counting returned ballots?
I know in MA early voting is nothing more than an absentee ballot completed at a polling place. If you know the registration of the voter, assumptions can be made by party.
I think it’s safe to say that 90% of early R votes are for Trump. Split the I vote 60:40 for Biden. And 80% Dems to Biden.
Early voters are generally pretty solid. Election Day voters might be swayed...but probably not.
These aren’t “vote,” but returned ballots. We are making the assumption they are for Republicans because Republicans ordered and returned them.
They could instead be registered Republicans who filled out their ballots for all Democrat candidates.
