{"version":"1.0","type":"rich","title":"79. D3 Start","description":"A static SVG bar chart displays a dataset of twenty numeric values, with each bar’s height and blue color intensity proportional to its value, and white value labels positioned atop each bar. The code uses D3 v4’s `scaleBand` and `scaleLinear` to map data indices to horizontal positions and values to bar heights, alongside `selectAll`, `data`, `enter`, and `append` to create the SVG rectangles and text elements. The visualization demonstrates a basic D3 bar-chart setup without animations or interactivity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7a0e3af5d53e46a28de1ea330d45e5a9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
