{"version":"1.0","type":"rich","title":"Bar Chart","description":"A bar chart displays 100 randomly generated numeric values as vertical bars, with bar heights proportional to the data. The bars are colored using a D3 linear scale that maps index positions to a gradient of blue, orange, red, and purple. The visualization is built with D3.js (version 3.5.5) using SVG rendering, where `d3.scale.linear` handles both color and height scaling, `d3.scale.ordinal` positions the bars along the x-axis, and `d3.select` appends the SVG container and rectangles. Data originates from a JavaScript loop pushing random values.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-2663514c0c95748f8544cab2183f30f5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
