{"version":"1.0","type":"rich","title":"tests","description":"This visualization plots air quality index (AQI) values over time, with each point colored by the main pollutant type. It uses the vega-lite-api library to construct a scatterplot with tooltips showing AQI value and pollutant. A horizontal red rule line is also drawn at a fixed y-value of 20, though its significance is not labeled. The data is loaded from a CSV file hosted on GitHub using d3.csv, and the visualization is rendered with Vega-Lite in an SVG view.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dd8bd00c6af8470da3386d86242747cf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
