The data given indicates the dynamic number of annual salaries of the 5 given professionals reported in 2001 to 2015. The most noticeable features was recorded by software engineers striking growth from the lowest rank in 2011 to the top in only 4 years,that reached above 225, while since the data recorded until 2011, the number remained stable in around 50.
The data also reported two data that have stable growth, the data scientist and computer engineers, but the amout was still data scientist at the top between these two data, which was the top numbers along 2002-2013, whisch was 11 years, from 75 to almost reached 225 at the latest data. While computer engineers also rose from around 50 to approximately 200.
The last 2 data are civil engineers and mechanical engineers. These two data had a different stage. Civil engineers had a stable data number with a slight upward at 2014, while mechanical engineers had an unstable data with a dropped in 2001 until 2005 then stable for 4 years and increased again until the latest recorded data with the number of the first and latest data almost the same with a very slight climb, not reaching 10.
