{"version":"1.0","type":"rich","title":"Cars HeatMap 01","description":"This interactive visualization displays the performance of various car models across multiple dimensions, specifically showing the relationship between a selectable metric, such as Acceleration, Displacement, or Horsepower, and fuel efficiency (Miles_per_Gallon). The view is structured as a small multiples grid, with each panel representing a different country of origin. The visualization uses Vega and Vega-Lite’s API to perform a KDE2D density estimation, which is then rendered as a heatmap using the `viridis` color scheme. Users can dynamically adjust the smoothing bandwidth, cell size, and color scale resolution, while a legend shows the normalized density probability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/27717adcc544467ea286625a91980f05?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
