{"version":"1.0","type":"rich","title":"Assignment 3 - Interactive Stacked Bar Chart","description":"This interactive stacked bar chart visualizes daily activity intensity for multiple users, sourced from Fitbit data in `dailyIntensities_merged.csv`. A dropdown menu switches between users, displaying four stacked segments—inactive, light, moderate, and intense activity—as proportions of a 1440-minute day. Built with ECharts 5.3.2, it uses the `bar` series with `stack: 'total'` for the bars, and adds translucent connecting polygons between adjacent bars via the `type: 'polygon'` element to highlight temporal transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/adb91daff6d64053a60f9cd40ed6f954?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
