{"version":"1.0","type":"rich","title":"Final Project","description":"This example visualizes air quality patterns, comparing SO2, particle, and NO3 concentrations across 31 U.S. states from 2008 to 2018 through animated line charts. Users select a pollutant via radio buttons, triggering an animation that reveals trends over time. The visualization uses D3.js v4 with SVG rendering, featuring a custom color palette for state-specific lines. The code integrates React for structure and employs D3’s data join and transition methods to update the chart dynamically, with data embedded directly in the script.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a158eda2f76946c289edf56bb8416097?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
