{"version":"1.0","type":"rich","title":"First Project Prototype – Sleep & Stress Bar Chart","description":"This grouped bar chart shows how average sleep duration varies across three stress-level bins (low, medium, high) for females and males, revealing that higher stress corresponds to fewer sleep hours. Built with D3 v7 and React, the visualization loads CSV data via `d3.csv`, aggregates with `d3.rollups` and `d3.mean`, and renders SVG bars through `d3.scaleBand` and `d3.scaleLinear`. A Tableau10 color scale encodes gender, while value labels and a small legend clarify the comparison.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d461d9675d6e40069b719c869c40aa39?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
