{"version":"1.0","type":"rich","title":"Untitled","description":"This interactive visualization maps the U.S. daily cigarette smoking rate from 1996 to 2012 across counties, showing changes over time through a choropleth map with a slider. A tooltip displays each county’s 1996 and 2012 rates along with the change. The visualization uses D3 v4’s `d3.geo` module with the Albers USA projection, `d3.nest` for data organization, and `d3.scale.threshold` for color coding, rendering SVG paths for counties and states. Data comes from the Institute for Health Metrics and Evaluation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b6aa6a15af204949a4c723e2a739c002?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
