{"version":"1.0","type":"rich","title":"Fork of Bubble chart","description":"This visualization shows the relationship between popularity and valence for Spotify artists, using a bubble chart where each circle represents an artist. The x-axis maps average popularity, the y-axis maps average valence (musical positivity), and the bubble size indicates the number of tracks per artist. Hovering over a bubble reveals the artist name and track count via a tooltip. The code loads CSV data with d3.csv, aggregates it using JavaScript `reduce` methods, and renders SVG circles with D3 v4 scale functions for positioning, size, and color.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/307cd4b0f90447479967232e9994e663?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
