{"version":"1.0","type":"rich","title":"NYC Air Quality Area Chart","description":"This area chart tracks NYC PM2.5 air pollution levels from February to May 2020, showing a decline in particulate matter during the early COVID-19 period. The visualization uses D3 v5 with an SVG rendering, employing `scaleTime` and `scaleLinear` for axes, an `area()` generator with `curveBasis` for the smoothed fill, and `axisLeft`/`axisBottom` for ticks. Data is loaded from a local CSV file via `d3.csv` and mapped to the weekly measurements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1492dd8e09a54aff897f89e179b36924?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
