{"version":"1.0","type":"rich","title":"population density_9","description":"This example presents two side-by-side SVG charts analyzing population data from a CSV file loaded from GitHub. A scatter plot maps population density per square mile against growth rate, with circle size proportional to 2023 population, while a bar chart displays total population per country. Both charts include interactive tooltips and axis labels. The visualization uses D3 v7 APIs including `d3.csv`, `d3.scaleLinear`, `d3.scaleBand`, and `d3.axisBottom`/`d3.axisLeft`, rendering entirely with SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ea0a4c63affa4cd9b09bff1f7a8906c3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
