{"version":"1.0","type":"rich","title":"fresh block","description":"A simple bar chart displays fifteen red bars with blue outlines, each bar’s height proportional to a numeric value in a static array. The visualization uses D3 v4 with an SVG renderer, employing `d3.scaleBand` for the x-axis positions and `d3.scaleLinear` for the y-axis scale. Bars are drawn as `rect` elements, with heights mapped from the data and vertically aligned from the baseline upward. The chart is generated directly in the browser via Blockbuilder, with no external data source beyond the hardcoded array.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-f093ff7ecf0a96d2b59f179747c8cb96?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
