{"version":"1.0","type":"rich","title":"Infovis","description":"A scatterplot of Swedish municipalities shows the relationship between municipal tax rate and average income, with circle size encoding mean age. Each point represents a municipality, colored in semi-transparent steel blue over a white stroke. The visualization uses d3.scaleLinear for x, y, and radius scales, d3.axisBottom and d3.axisLeft for gridlines, and SVG circles rendered from data parsed from a local CSV file. A dropdown menu, powered by a custom dropdownMenu function, is present but currently offers only placeholder options.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1d68e6f2e76646b0a953d064b590ce0b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
