Very cool project! I was leafing through your dashboard and had a few suggestions:
[1]: Given that the minimum transaction relay fee of Bitcoin Core is now 0.1 s/vB, perhaps it would make more sense to express the AVG TX FEE with at least one decimal precision.
[4]: I think in the Mempool status chart, "Mempool size" is referring to two different things. The mempool limit of 300 MB refers to the total memory usage of deserialized transactions, not total virtual size of transactions. Since Mempool Space is currently reporting about 35 MvB of transaction data, but 185 MB of memory usage, I think you’re showing the former, but comparing to the limit for the latter.
[6/7]: Active Nodes by Country is interesting, but node density by country seems a bit odd. When speaking about density, I would have expected the node count per capita rather than per country. E.g., France and USA’s node count per capita is very similar, but USA has twice the nodes of Germany, but 4× the people.
[8] Similarly, El Salvador has a tiny population compared to Brazil and USA, but a respectable count of businesses on the BTC Map.
