{"version":"1.0","type":"rich","title":"Fork of Vega-Lite API Template","description":"This example visualizes the Auto MPG dataset from the UCI Machine Learning Repository, plotting each car’s fuel efficiency (mpg) against its horsepower. Each circle’s size encodes vehicle weight, while color distinguishes the region of origin, and hovering reveals the car’s name. The visualization is built programmatically using the Vega-Lite API (`vl.markCircle`, `vl.x`, `vl.y`), with data loaded asynchronously via `d3.csv`. Rendering is handled by Vega and Vega-Lite, with tooltips provided by Vega-Tooltip, and custom axis and label styling is applied through a shared config object.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/365288bc40744615a60d897c7b8b78f3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
