{"version":"1.0","type":"rich","title":"Lifting Log v6","description":"This visualization plots personal exercise activities over time as a dot matrix, showing which muscles were worked on each day for the past 24 days. Black circles represent executed workouts, while white circles with black outlines indicate planned exercises. The horizontal axis shows dates, and the vertical axis groups activities by muscle category, with dashed lines highlighting gaps since each muscle was last exercised. Built with D3 v6, it uses scalePoint and scaleTime for axes, group for data aggregation, and SVG circles and lines for rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ded92004ecac426c91bc949ced05fb68?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
