**Numbers are not reality**
|
||||
|
||||
## Features :
|
||||
|
||||
- sync X axis at a value
|
||||
- reset (broken, need reload page too)
|
||||
- set a limit for y axis
|
||||
- select first and last day
|
||||
- select data source (confirmed, deaths, recovered)
|
||||
- select scale (log/linear)
|
||||
- select countries
