The scatter plot dots are way too small!

In some of the scatter-plot graphs, the scaling is off and the graph becomes illegible. This seems to happen when the number of cases grows too large; it's evident in most country graphs. It only affects scatter plots.

Examples:

The latter shows the crossover in action - some of the countries have legible-sized plot dots, others do not. And looking backward through revisions you can see the issue start with the US and then gradually take over all countries. I would assume this is very easy to fix; if it's a glitch in the graph software raising the ymax would be likely to do it.

Entirely unrelated commentary that isn't really an issue: India's BA.2.75 graphs are a bit misleading because all or most of their BA.2 is actually a significantly more contagious sub-variant (BA.2.36 maybe?) that would itself be worthy of monitoring had not BA.4/5/2.75 come along. Splitting off this lineage might make things a lot more linear (on the log plots).
