{"version":"1.0","type":"rich","title":"Bar chart with a Sequential color scale","description":"This bar chart displays average engine horsepower for seven car manufacturers, sorted from lowest to highest, with bars colored according to a sequential red color scale that maps horsepower values to increasingly darker shades. A yellow tooltip appears on mouseover, showing the exact manufacturer and horsepower value. The visualization is built with D3 v6, using `scaleBand`, `scaleLinear`, and `scaleQuantize` for positioning and color encoding, along with the ColorBrewer Reds palette and the d3-legend library. Data is loaded from a CSV file via `d3.csv`, and rendered as SVG rectangles with interactive hover effects.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/49e90bc1aecb4291be1e9760e5d26cbe?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
