Found this interesting and I admit I do have Suns bias, but nice to see after 10 years of putrid play

What exactly does this TPA says? Graph looks funny. Nice pictures though.

As such, the formula for TPA is rather simple. It’s broken down into two parts—offensive points added (OPA) and defensive points saved (DPS)—and each is calculated in the same vein.
OPA is derived by adjusting offensive box plus/minus (OBPM) to account for the number of possessions the player in question is present for. Similarly, DPS is derived from a similar adjustment of defensive box plus/minus (DBPM) with that same number of possessions. OBPM and DBPM, both calculated by Basketball-Reference.com, estimate the per-100-possessions value of a player on either end of the court.
Add OPA and DPS together, and you have TPA. A score of zero indicates a player was perfectly average (by no means a bad thing for rookies or lifelong end-of-bench players), while anything positive means they were better than an average-level replacement.
At the heart of the theory is this comparison between two hypothetical players:
Player A makes an average team 5 points better per 100 possessions than an average player would in his spot, and he plays 500 possessions.
Player B makes an average team 10 points better per 100 possessions than an average player would in his spot, and he plays 250 possessions.
Player B is more effective on a per-possession basis—twice as effective, in fact. But Player A spends twice as much time on the court. Theoretically, they should have identical values, as they would both add 25 points to an average team.

total points added
The concept of total points added (TPA). We're looking at both defensive and offensive effectiveness on a per-possession basis while also incorporating the amount of playing time the contributor in question receives.

This next one might display it easier.

He's a versatile defender, his shooting mechanics look great, and he's just playing with way more confidence. He came in as the youngest player in the league, and was obviously really raw, but it's nice to see its starting to come together.

It shows minutes on that so you can kind of filter out small sample size if needed,but typically guys who add on offense and defense don't get a lot of minutes anyway so are on the left, usually below the line.
There are other charts that break down offense and defense.
Here you can see offense and defense....further to the right is offense, higher up is defense, so you see a guy like Trae, way ahead on offense, but really bad on defense.
Then a guy like Bridges really on high defense, and good on offense as well.
Luka solid on offense, neutral on D.
Ayton, solid on defense, slightly positive on offense, which may be surprising based on his rookie year play.

I don't believe this tells you anything how starting 5 should look.

I am sure it does not tell you anything since you said so. It shows me Huerter is having a decent season. This is night and day compared to last season. He was not a neutral value defender or offensively efficient player last season. This season he is.
