{"version":"1.0","type":"rich","title":"Vega-Lite API Template 1216","description":"This visualization uses the Vega-Lite API to display a scatter plot of UCI Auto MPG data, plotting miles per gallon against horsepower. Each circle represents a car model, with color encoding the country of origin, size encoding weight, and tooltips revealing the car name. The code fetches CSV data via `d3.csv`, then builds the chart programmatically using functions like `vl.markCircle` and `vl.x().fieldQ`. The visualization renders as a full-window SVG with a custom dark theme, with axis styling and tooltip formatting configured for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/025d6073691b4838bc2ecd412e48457d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
