{"version":"1.0","type":"rich","title":"Data Visualization Homework 9: Spotify\n      Tracks Dataset","description":"This visualization explores a Spotify tracks dataset through multiple interactive views: a grid of per-attribute pie charts and histograms, a correlation matrix, a stacked bar chart of genre popularity, and a scatter plot relating artist and album popularity. Users switch views via dropdown menus and filter by genre. D3 v5 handles the SVG rendering, animations, and scales, while the jeezy and data2grid libraries compute the correlation matrix. The stacked bar chart uses `d3.stack` and a custom tooltip, and a legend highlights categories on mouseover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cb124cdde9074b6d874d8731acebea82?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
