Quick post about a prime example how NOT to visualise data trends in Europe.

Reading the news I came across the below visualisation trying to show how the weekly cases are developing:

A few key points
• One should always follow how people are reading. In this case: Left --> Right
• There is a reason it is called visualisation – you try to use visual elements to make people comprehend information
• In the above example having to read the dates makes the information much harder to understand and takes longer

So next time you have to visulise data, ask some basic questions. What I am trying to convey? Who is it for? to name a few.
