{"version":"1.0","type":"rich","title":"World Population","description":"This scatterplot visualizes world population data, plotting each country’s growth rate against the log10 of its population density. Circles are sized by population and colored by continent, with a dropdown filter and a range slider to narrow results. Hovering reveals the country name and dashed guide lines. The implementation uses D3 scales and axes, `d3.sliderBottom` for brushing, and SVG elements for rendering, with data sourced from a custom dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9aaea5c82a564afead882d4a64b96200?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
