Yesterday, I did some Kusto queries to understand more the situation in Spain, UK, Brazil, US, China, Iran, Italy and other parts of the world using COVID-19 (Coronavirus) dataset.

If you want to try as well with your country, see below some ideas of Kusto queries.

Deaths in Spain by the time series.

CoronaVirus
| project CountryOrRegion, Timestamp, Deaths
| where Deaths > 10
| order by Deaths
| where CountryOrRegion == "Spain"
| render linechart ;

Deaths, Confirmed and Recovered cases in Spain by the time series.

CoronaVirus
