{"version":"1.0","type":"rich","title":"D3 test","description":"This example shows a simple bar chart of 20 numeric values, rendered as SVG rectangles with a blue gradient and white labels above each bar. The chart uses D3.js version 3.5.5 to bind data to SVG elements, scaling bar height by a factor of four and positioning bars with a fixed padding. The visualization is generated entirely from an inline dataset within the HTML file, with no external data source, and demonstrates basic D3 selection, data joins, and attribute manipulation for static presentation.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-8d91b9f00d33746e8a63?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
