{"version":"1.0","type":"rich","title":"fresh bar chart","description":"A simple bar chart visualizes eight hard-coded values, with each bar’s height proportional to its numeric data point. The bars are rendered as blue SVG rectangles with white strokes, drawn from a baseline at y=300 upward, on a 1000×1000 canvas. Using D3 v4, the code selects all `rect` elements, binds the data array via `data()`, and positions each bar with `attr('x')` and `attr('y')`, while `attr('height')` sets the bar length. The chart uses no axes or labels, focusing purely on raw value comparison.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-bc408096f7494e36c1f40d15a0521b79?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
