31:T5a2,md`# Original description This notebook intends to offer a complementary view on the global number of cases of Covid-19 infection published daily by [Johns Hopkins’ CSSE](https://systems.jhu.edu/). **Scale**. By using a logarithmic scale, we can visualize more countries—even if they are to this day less infected than the province of Hubei, China whence the epidemics originated. **Coordinates system**. By setting the *x* and *y* dimensions to something else than _confirmed cases_ vs _time_, we can compare the countries’ (or provinces’) trajectories in a different space. For example, while Italy and Iran presented roughly the same numbers of cases and deaths on March 3rd, the dynamics of the infection were clearly following different patterns. **Trend lines** help limit the clutter and focus on the current dynamics in each country. *These trends are not to be taken as a model that would persist in the future.* The data is also grouped in a format that might be easier to work with than the original format. _This notebook was prepared for the [LIRIS M2i project](https://projet.liris.cnrs.fr/mi2/), which researches (among other things) visualisation tools for cumulative data. Comments and suggestions welcome!_`32:T21d0,chart = function*(options) { options = options || {}; const w = options.width || width, height = options.height || w * 0.7, axisX = options.axisX || "date", axisY = options.axisY || "confirmed", perMillionX = axisX.indexOf("per million") >= 0, perMillionY = axisY.indexOf("per million") >= 0, groupBy = ((perMillionX || perMillionY) && options.groupBy !== "country" && options.groupBy !== "province") ?
