FWIW the visual graph style IDE is used to write scripts for 3d design programs Rhino 3d (Grasshopper plugin [0]) and Revit (Dynamo). It's pretty popular among architects and the like.
Pace comments that STEM majors are not part of the trend, consider this: I started my undergrad education following the dot com bubble years and was dissuaded to pursue compsci. I went into civil (structural) engineering instead. Over half of my civeng classmates would go to postgrad education -- in engineering, law, whatever -- precisely because of the inability to find a job in civil engineering. About a third of my Master's class (structural engineering @ Berkeley, a top school in the field) couldn't find a job upon graduation. I landed a job purely by accident (with a 3.75 GPA), where a better qualified classmate of mine took another year to find one. I haven't kept track of what happened to the rest.
