{"version":"1.0","type":"rich","title":"Music Format","description":"This visualization shows the evolution of music format sales in the United States from 1973 to 2019, with each format appearing as a colored band that widens to represent its annual revenue. The chart uses a bar-on-bar layout where a white background mark for each year is overlaid with the format-specific segments. The visualization is built with React and D3 v5, employing `scaleLinear`, `scaleBand`, and `scaleOrdinal` for scaling, while the `nest` and `sum` functions aggregate the raw sales data. The background image and SVG rendering create a stylized, poster-like presentation of the dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/97a79e76024b4fe1997e4657853118eb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
