A Spotify listening data dashboard plots daily listening patterns as circles, with the x-axis encoding the day of the month, the y-axis showing the network, and circle size reflecting like counts. Color indicates sentiment, with tooltips revealing exact dates. Built using Vega-Lite API for declarative chart specification, it loads CSV data via D3’s `csv` function and renders through VEGA and Vega-Lite libraries with a custom configuration for styling.
