{"version":"1.0","type":"rich","title":"A5-Line Chart in D3","description":"This example loads the Spotify 2023 dataset from a CSV file and visualizes three metrics—total streams, average energy, and average valence—as separate colored lines across the release day of the month. Using D3.js v7, the code aggregates data with `d3.rollups`, scales the axes with `d3.scaleLinear`, and draws lines via `d3.line()`. The SVG chart includes labeled axes and a legend, with all rendering handled through standard SVG elements in an 800×500 viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0ff332935c9d44bcaa02827093f12920?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
