{"version":"1.0","type":"rich","title":"Week 7 – Project Momentum: Color assignment.","description":"This visualization presents a 100% stacked bar chart showing the distribution of sleep disorders (None, Insomnia, Sleep Apnea) across three stress-level bins (Low, Medium, High), with a dropdown filter for gender. Built with D3 v7, it uses `d3.scaleOrdinal` for color assignment, `d3.stack` for stacking, and SVG rendering with animated transitions via `transition().duration(400)`. The chart dynamically updates its title to reflect the selected gender and sample count, drawing from the Sleep Health & Lifestyle dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b1ecb3b7a36040fc995f28b800b9c1bf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
