Log-log plot of new vs. total Covid-19 cases by country
Log-log of daily growth vs total cases is a neat graphics hack, one I'd not seen before, let alone thought of.FT have been headlining a semi-log plot of deaths per country, normalised to days after the first ten deaths were reported.https://www.ft.com/coronavirus-latestBecause dead bodies tend to behave characteristically, are inconvenient both directly and via surviving relations, and present a smaller testing target (about 1% of total cases) as well as representing a full course-of-illness endpoint, these data should be generally more reliable and cross-regionally consistent than confirmed cases.  Deaths are, however, lagged by about two weeks.FT also provide numerous other graphical representations, including an excellent small-multiples (Tufte fans) matrix of multiple countries' case trajectories.My view is that all serious reporting should lead with similar visualisations.Wikipedia's COVID-19 pages have similarly featured semi-log plots from early on, as does Worldometers.https://en.wikipedia.org/wiki/2019–20_coronavirus_pandemic#D...https://www.worldometers.info/coronavirus/(Numerous additional pages with regional and specific behavioural characteristics within both sites.)Anoter data visualiser, allowing arbitrary multi-country comparisons:https://rys.io/covid/
