{"version":"1.0","type":"rich","title":"Marketing Data Bubble Chart","description":"This D3.js v7 bubble chart visualizes marketing campaign performance by plotting clicks on the x-axis and conversions on the y-axis, with each circle’s radius scaled to its budget. The SVG output uses `d3.scaleLinear` for axes, `d3.scaleOrdinal` with `d3.schemeCategory10` for categorical coloring, and a static legend listing each campaign. The chart renders a hardcoded array of ten campaigns, encoding three numeric variables through position and area.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1592ce7a5ed34ddeafdf6d380b2d3258?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
