This is the second version, first version is here.
These are the students of 1 year at my school. The year is the year they graduated at their last school. I've found a strange pattern: the people who did nothing three years before entering this study (or dropped out somewhere) scored almost the best.
You can see the different groups of students divided on the Y ax to compare them. Every circle is an student, the red ones are the averages for the whole group. 'Gemiddeld' means average and all the other words are subjects at my school, which you can select to see how everyone did.
The idea is that the graph simulates a race where each group is matched to eachother, the year in red is the one with the highest average for this selection.
