{"version":"1.0","type":"rich","title":"Q4","description":"This interactive visualization, part of a multi-chart music data explorer, presents a bubble chart analyzing Spotify artists. It plots each artist's average song popularity on the x-axis against their average valence (musical positivity) on the y-axis, with bubble size representing the total number of tracks per artist. Hovering over a bubble reveals the artist's name and track count via a tooltip. The chart is built with D3.js v4, using `d3.scaleLinear` for axes and bubble radius, `d3.scaleOrdinal` for colors, and loads data from a CSV file. It references other linked bar charts for song genres and artist popularity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6f7493fe5a2c4e4b863dd9493ccfd2c0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
