{"version":"1.0","type":"rich","title":"A6 Bar","description":"This bar chart displays the average number of forward gears for the top 10 car manufacturers from a CSV dataset, with bars colored by a sequential rainbow scale. It uses D3.js to load and aggregate data with `d3.csv` and `d3.rollup`, then renders horizontal bars via SVG rectangles. The chart includes axes, labels, and a color legend generated with `d3-legend`’s `legendColor`, while the color mapping uses `d3.scaleSequential` with `d3.interpolateRainbow`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a587cc8841b2440da5cd8975d5d4bf72?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
