{"version":"1.0","type":"rich","title":"Scatter Plot Matrix graph","description":"This scatter plot matrix shows the relationships between air quality (AQI), temperature, and municipal greenhouse gas emissions in San Francisco across fiscal years 2020–2022. Color-coded points for each year visualize correlations between all variable pairs in a grid of small multiples. Built with D3 v7, the visualization uses `d3.csv` for data loading, `d3.rollup` to aggregate emissions data, and `d3.scaleLinear` for axis scales. The SVG rendering applies a categorical color scale via `d3.scaleOrdinal` and draws circles with SVG paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/75a047e5d3824849a35d75a8abf90147?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
