{"version":"1.0","type":"rich","title":"question 3","description":"This scatter plot shows the relationship between horsepower and highway MPG for vehicles, with each point's shape encoding the vehicle make. The visualization uses D3 v7 APIs including `scaleLinear`, `scaleOrdinal`, `symbolsFill`, and `symbol` to map data to positions and shapes. Axes are rendered with `axisLeft` and `axisBottom`, while a custom `shapeLegend` displays the categorical mapping. The data loads from a CSV hosted on GitHub, and the plot fills the browser window, updating dynamically as new data arrives.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7cea515a43134181bc3f8e33276a2092?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
