{"version":"1.0","type":"rich","title":"Song's Note: Start & End - With choice","description":"This interactive D3 visualization explores a MIDI song by displaying each track's notes as horizontal bars, with x-position indicating start time and bar width representing duration. A color legend for MIDI files lets viewers select which song to examine, while a second legend filters individual tracks. The scatter plot uses `d3.scaleLinear` for axes and `d3.scaleOrdinal` with `d3.interpolateViridis` for note colors, with `transition.duration` and `.delay` animating the bars. Data comes from the Million Song Dataset, rendered as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3d5d4f4223f143b29a8834725b53eb6b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
