{"version":"1.0","type":"rich","title":"interactive graph","description":"This interactive scatterplot displays air quality index (AQI) values over time, plotting each daily measurement as a point with a fixed size and full opacity. Hovering reveals the exact AQI value via tooltip. The visualization loads daily API data from a CSV file using `d3.csv`, then builds the chart with the vega-lite-api library, which registers Vega and Vega-Lite and renders to SVG. The chart automatically fits the window size and applies custom styling for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2bfcdc6ef1ab44348187f3e00e7caf03?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
