{"version":"1.0","type":"rich","title":"Combined Chart","description":"This combined chart displays daily steps, calories burned, and heart rate data for a fitness tracking scenario. Bars show raw step counts, while a red line represents calories burned and a green line shows heart rate, using separate scaling factors to align these different magnitudes on a shared axis. The visualization is built with the D3.js v7 library using a CSV dataset loaded from a GitHub gist. It combines an SVG bar chart with two line charts, utilizing D3’s scaleBand, scaleLinear, axis, and line generators to render the layered graphic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/da37c1fc8c7e4651821790d6b50f9c27?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
