Skills on the move: the skills whose demand changed the most over the last few weeks.
The blue number on the left is how many open postings name that skill right now. The line shows how that moved week by week. The arrow and % on the right are the overall trend - the slope of a line fitted through all the weeks, so one odd week doesn't skew it (green = rising, red = falling).
Order: sorted by how much the demand actually moved - postings gained or lost - biggest first.
