{"version":"1.0","type":"rich","title":"Lesson 6","description":"This visualization displays the relationship between vehicle weight, horsepower, and fuel efficiency using the auto-mpg dataset. A scatter plot maps weight on the x-axis and horsepower on the y-axis, while both the size and color of the circular marks encode miles per gallon, with tooltips revealing car names. It is built with the vega-lite-api, which wraps Vega-Lite and Vega, and loads data via d3.csv. The chart fills the browser window with a fit autosize and uses custom axis and label styling from a config object.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d40f3b200b304402b900680d333db8d8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
