{"version":"1.0","type":"rich","title":"ice7_task3","description":"This dark-themed area chart visualizes the average monthly listeners of top Spotify artists grouped by their debut year. The chart uses a blue gradient-filled area with a lighter line overlay, and interactive data points display exact values via a tooltip on hover.
