Showing the Bitcoin fee movement in dollars is quite irrelevant, at least for any analysis. The price of Bitcoin can only indirectly affect the fee, and only if it causes an increase or decrease in the number of transactions.
The value in $ is what people care about when buying something.
Do you think somebody would care if they paid 10,000 sat/vb if that's 1 cent?
People still think in $, you buy stuff that's priced in $ so you will think about how much of that you spend transferring it, if Bitcoin reaches 700k do you think anyone would say, oh, it's just 10 sat/vb let me pay 40sat/vb for it as I got used to it or will they say that no way in hell are they paying $100 to buy something a visa card charges zero and doge a quarter of a cent?
Anyhow, sat/vb or USD per tx, fees are still lower by both metrics right now compared to December, on chain usage other than ordinals is simply dead, I hope some migrated to LN, but I'm still waiting for true signs of this.
For example, the current fee is a modest 232 sat/vB and the current value of Bitcoin has no significant effect on it.
I don't get this one...
