This dark-themed dashboard displays Spotify Premium subscription price increases from 2024 to 2025 across four plans: Student, Individual, Duo, and Family. Each plan is shown in a card with the absolute euro increase and the percentage change. The React app maps over hardcoded data, computing the difference between “vorher” and “nachher” values, and renders the results in a responsive CSS grid. Styling uses Tailwind-like classes, while no D3 charting functions are invoked.
