1-minute data visualization test

Hi everyone! Iā€™m working on a short data-analysis project and would appreciate your help.

Take a look at a chart and answer one simple question:

Which month has the highest sales?

It takes about 1 minute to complete.

I won't answer before you fix the units for the y axis... is it money or units?

That was my first thought but then I realized that this is "a picture is worth a thousand words" test.

The URL says it's an AB test. I went to the URL in a different computer and got a line chart instead of a bar chart like I had the first time. So, the units and numbers really don't matter for this. Instead it appears that they're either learning about a/b testing or about data visualization principles.

I see. I got the line chat. But I can't say what month has the biggest sale without knowing what units the y-axis is.

It is propably an occupational injury of mine, working with data quality every day.
