{"version":"1.0","type":"rich","title":"multi line","description":"This multi-series line chart displays fitness activity trends over 160 days, comparing steps count, calories burned, and workout minutes on a single scaled y-axis. Built with D3.js v7, the visualization renders three distinct colored lines—purple, blue, and green—from a CSV dataset, with data points filtered to every tenth day for clarity. The SVG output includes axis labels, a legend, and gridlines, using D3's linear scales and line generators. Steps and workout minutes are normalized to align with calorie values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/366ed12fb068425fb5f8d8fc31fc9106?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
