{"version":"1.0","type":"rich","title":"Assignment 6 -- Bar chart with a Sequential color scale","description":"A bar chart displays average engine horsepower for seven car makes, sorted from lowest to highest, with a sequential red color scale encoding the horsepower value. The chart uses D3 v6 with SVG rendering, including axes, a color legend, and a tooltip that shows the exact value on hover. The code reads data from a CSV file, applies a quantized color scale from the ColorBrewer library, and uses the d3-legend API to generate the legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dbda4a96642946bf8db3ed42546325c8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
