{"version":"1.0","type":"rich","title":"Fork of Vega-Lite API Template","description":"This example uses the Vega-Lite API with D3 to render a scatterplot of automobile data from the auto-mpg.csv dataset. It plots miles per gallon on the x-axis against horsepower on the y-axis, with points colored by country of origin and sized with a fixed 300-pixel radius at 50% opacity. The visualization is generated declaratively using `vl.markCircle`, `vl.x().fieldQ`, `vl.y().fieldQ`, and `vl.color().fieldN` to encode the quantitative and nominal fields, with tooltips showing car names. Data is loaded asynchronously via `d3.csv` before the chart is rendered into the DOM.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7fd769e8742d4fddaae8238a28516aea?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
