{"version":"1.0","type":"rich","title":"Activity_6_Q4","description":"This bubble chart visualizes the relationship between GDP, population, and economic growth for ten global cities. Each circle's x-position maps to GDP, y-position to population, and radius to growth rate, with individual city colors shown in a legend. The visualization uses D3 v7's `csv`, `scaleLinear`, and `scaleSqrt` functions to load the CSV data and map values. It renders to SVG with axis labels and tooltips, positioning the legend at the chart's right edge.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1970dcb8a3ed44c6aee31fb302573bcc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
