Why all graphs are cummulative instead of new cases for that day? It's harder to notice how it is growing that way (i.e. more or less new cases than the previous days) and harder to see if it is going exponential, lineal or whatever. And, of course, forces to use log scales because the accumulated number is already high.

At least for networking graphs is more meaningful to see difference from the actual from the previous commulative total, than watching the total for a network interface.

Another, at least for me, misleading use of graphs is to show the cummulative total people that ever got sick, instead of the current amount of sick people (taking out the recovered, and maybe the dead ones).

I know that how the measurements are done in most places is rigged, as not everyone is checked, and there are a lot of people that are asymptomatic, but that happens with both the new cases and the cummulative ones. Showing the cummulative numbers don't take out that rigging.
