You've highlighted a logarithmic graph. I think you're pointing out the rate is not as steep, but if you look at the numbers on the Y Axis:

The scale in each box jumps from 1 to100 to 10,000 to 1,000,000
That next box is
ten million. The whole purpose of a logarithmic scale is to deal with huge numbers. That is why the curve flattens out because the 'Y-axis' increases by one digit each time. What you've actually demonstrated is a massive jump in cases.
Here are the numbers based around each month. I've started in May to bring in the increased testing.
May - 1,141,000
June - 1,877,000 (64% monthly increase)
July - 2,789,000 (48% monthly increase)
August - 4,798,000 (72% monthly increase - OMG)
September - 6,293,000 (31% monthly increase - Phew!)
If Octobers numbers drop below 31%, you can hope there's a slowing. I think the August increase put the frighteners on a few states and some measures were taken?
