The infographics are dismal. The bars in 'Average Salary by Specialty' indicate that Python developers make twice what Javascript devs earn, while in reality it is around 10%. When you look at Java, an approximate 10% difference between Junior and Midlevel results in much more similar bar heights. What's missing is where the numbers are coming from, how many replied and whether it is in any way representative. The numbers for Germany are very odd. 24k for a designer is pretty close to the poverty line, I believe. Is that before or after tax? I guess it suffers from a lack of participation from many non-anglosaxon countries, so I would not use any of these numbers in actual interviews.
