This animated scatter plot visualizes student enrollment trends across different degree types—bachelor's, master's, PhD, and jobs—tracking the number of students going abroad over time. The visualization cycles through each category every two seconds, updating both the data and the symbol shape (circle or square) to represent the current category. Built with D3 v3, the reusable `scatterPlot` function manages scales, axes, and transitions, while the main script loads CSV data from a GitHub gist and drives the animation loop using `setTimeout`.
