{"version":"1.0","type":"rich","title":"Bubble chart","description":"This bubble chart visualizes Spotify track data, plotting the average popularity (x-axis) against the average valence (y-axis) for each artist, with bubble size representing the total number of tracks. The chart uses an SVG renderer with D3.js v4 and a color scale from `d3-scale-chromatic` to differentiate artists. Hovering over a bubble triggers a tooltip displaying the artist name and track count. Data is loaded from a remote CSV file and aggregated using JavaScript's `reduce` method to compute averages and counts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/43036e9782e144fd8c395259d6e0694b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
