{"version":"1.0","type":"rich","title":"Vega-Lite API Template fast iteration","description":"This example demonstrates rapid iteration with the Vega-Lite API by rendering a scatter plot of automobile data from the UCI Machine Learning Repository. It shows the relationship between highway miles per gallon, engine displacement, model year, and city MPG using circle marks with opacity. The visualization is built programmatically using `vega-lite-api` to construct the specification, then rendered as an SVG via Vega and Vega-Lite, with tooltips handled by `vega-tooltip`. The code uses `d3.csv` to fetch data, applies custom axis and label styling from a config object, and dynamically sizes the chart to fit the window.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/272a759ee2dd493095f2d21b3633b55f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
